So to start off the year I decided to post my first proper top 10 tier list based on my impressions of what we've seen in 2014, be it tournament results or theorycraft, and also based on my personal experience in local play. Characters go in this specific order:
1-
Low damage output and lack of kill moves means little when you have such a dominant neutral game with little risk and considerable reward. Personally, I find the choice of balance in her 1.0.4 changes questionable: I'd focus less on DMG/KB values of Fair and Bouncing Fish and focus more on reducing a little of their safeness. As of now Sheik's Fair is nigh nonpunishable, and amidst Fair, Nair, Needles and her mobility it's a herculean task to put her in the disadvantage for most characters as it appears risk vs reward is always in her favor. She has the offstage game to make up for her lack of kill moves, with UpB being amazing as it is for recovery (and for killing). Sheik has too many tools to dictate most MUs and she can overcome her only apparent weakness through smart and methodical play.
2-
Talking about Uair has become too mainstream, so let us not forget some of Diddy's other ridiculously strong moves, such as a spammable 5 frames Dtilt with respectable range that easily allows follow-ups; A Fair that rivals Marth's in speed (6F start-up), with good range, hitbox, can be auto-canceled with fast fall and does 12%; His mobility, how unforgiving he is against shields with dash grab and Monkey Flip, the kick variant of Monkey Flip with it's speed and bazillion active frames, Bananas that allow easy grab setups, the high damaging combos from Dthrow...it's scary to think how good he is even without his Uair non-sense. With that said, he's not a God and has his share of even MUs, usually against the other top tiers. His recovery is something that should be exploited more as it's his only weakness at first glance.
3-
When people joke about him being the El Fuerte of this game, it's accurate because just like El Fuerte in SF4, playing against a good Sonic is a game of patience and gamble. Differently from El Fuerte however, who doesn't get a lot of damage from his mixups, Sonic is VERY damaging for being the fastest and one of the safest characters in the game. 20+% of a Spin Dash into aerial hit-confirm is a huge reward for a character that can reset most bad situations with ease. With the mobility he is allowed to have from B specials and running, it's not hard to land his more risky moves like Bair (which is also a kill move) or his grabs which can be converted into a Bthrow, another potent kill move, or even position a smash attack against landings. Sonic's mobility by itself makes him very strong already, but his improved hitboxes (F-air lol), good damage and kill setups are just icing in the cake. I really expect him to increase even more in usage.

(2122 customs) In my opinion, one of the best pure rushdown characters in the game, only rivaling Sonic because of the hedgehog's ridiculous safeness. Having one of the best (if not the best?) horizontal aerial mobility with a 26 active frames Nair is just oppressive. That much aerial mobility with three very reliable launchers (Fair and Dtilt can both be followed-up until around 80%, plus Dthrow) gives them crazy setups. Aerials have great frame data and hitbox, Tilts are fast and the Smashes are devastating and not hard to land since it's easy to force mistakes from your opponent as you pressure them with hitboxes and frame traps. Helicopter Kick is arguably one of the best moves in the game as it's easy to setup and kills early while also being a good recovery; Feint Jump is majestic for both offense and defense, essentially being a third jump. Brawler can approach in so many ways and that might be his biggest selling point over Sonic and thus he might be more convenient in certain MUs.
And yolo Onslaughts is the most satisfying move to hit in the game
5-
She had significant (and justifiable) nerfs in 1.0.4 and, as my main character, the more I play against locals the more I see anti-luma tactics. With that said, she is still the queen of hitboxes and will still wall over half the cast with her disjoints and Luma shenanigans. Rosa is interesting because while she has a very strong defensive game, she can quickly transition to an aggressive play once she wins the neutral thanks to her dominant juggling and her ability to cover almost all opponent's ledge options (imo the best character at that), and can easily forces mistakes and convert them into kills because of her generous kill power. Luma still does a nice job halting pressure and breaking opponent's momentum, which is really helpful considering Rosalina's poor options for recovering from above and landing. In my opinion Rosalina is in the process of being "downloaded" by the meta-game but I believe she will continue to be a top character just because of her many good moves and the possibilities Luma allows. Let us not forget she still has potential for more development because of her unique gameplay.
6-
For reasons similar to Brawler: minus mobility and recovery, but plus command grab and a very good projectile. Hitboxes on some moves are kinda bogus, his rewards are good, he kills fast, egg-throw is godly, neutral B mixups works so well with his very good horizontal aerial mobility, hard to gimp, no apparent glaring weakness...character is just very solid, although he doesn't have as much non-sense as Sonic or Brawler. Really looking forward to the ascension of Yoshi's in the western side of the world, as I feel he can go even against all top tiers.
7-
I love ZSS because often I feel she fits as a true fighting game character. She can go rushdown but can also sit at mid-range playing spacing and footsies with Paralyzer, aerials and SideB. Good damage, top notch CQC and frame traps, lots of setups from Paralyzer, DownB and Dsmash, very hard to pressure both on and offstage because of her mobility and recovery options. Give her a platform stage like Battlefield and you have a mixup monster by improving the approaches of her aerials and her Dsmash options. She is not without flaws because of her inconsistency against certain hurtboxes and her poor grab, but tournament results both in the west and in Japan shows that her other attributes are enough to overcome such weaknesses most of the time.

Probably the best at edgeguarding to the point where losing the neutral against the rat is a bigger risk than it normally is against most characters, and speaking of neutral, he also doesn't care if he loses it because he can also reset the situation quite well. A very good aerial kit, be it for spacing, racking damage, confirming of throws or gimping. Thunderjolt is imo one of the best projectiles for covering approaches or forcing them. Quick Attack shenanigans allows good mixups that leads to very easy and safe damage. Pikachu can be very scary with momentum. I'm not sure how the Pikachu meta is going but I'd love to see more use of Thunder to break opponent's strings (such as Mario Utilts) since according to the recent frame data Thunder start-up is 1 frame (in the first frame the cloud is summoned). I'd probably put Pikachu higher but lack of more representation sucks.

Significant recovery problems apart, having 4 quite reliable kill moves (Bthrow, Uair, Bair, Nair) is a big plus in this game. Ness strength comes mostly from how well rewarded he is, be it from PK Fire, PK Thunder, grabs or aerials. In the neutral Fair and Nair are invaluable moves great at walling people. Despite the whole bad recovery belief, his double jump is godlike for all purposes: pressuring, spacing, recovering etc. I still feel he struggles against the more mobile characters like Sheik as Ness still relies on a bit of spacing to get his game going.

I feel too many characters can go here:
: Not as unsafe as I used to think and the right Monado Art at the right time can be such a huge game changer
: Despite recovery and landing weakness, his pressure and rewards are obnoxious
: Good character that can impose the flow of a lot of MUs because of how balanced and versatile his kit is
: Very good momentum based with good strings coupled with speed and safeness, despite his predictable kill moves
(rushdown set): I have seen zero gameplay of her in action, although in theory she sounds absurd
: aura tho
