I'll write my credentials but tl;dr I’m a scrub. Nevertheless, I'm making my list like all the other scrubs. I've included explanations so that people can make fun of my reasons for being as dumb as they are and I can learn from that.
Um...beat ajtwist in singles and 2Jar and PracticeMan in teams at KoC2. Haven't recently attended any other significant tournaments, although I have had regular smashfests with Tai, Wobbles, Axe, and Taj in attendance frequently (so they'd make good references). I play pretty even with Che$ and Neon if you can find any videos of us (Che$ prefers Wes but that'll just get him confused with the Samus player). Che$ has tended to beat me in close matches in tourney, I think Neon and I are like 1-1 or 1-2 in his favor.
1. Fox (+0 blink blink dead. And if that doesn't work, great horizontal mobility, fantastic spacing, juggling and upward kills)
2. Falco (+0 for being free offstage #MarthMain, though onstage he's got the best combo game of any character)
3. Sheik (+1 for great priority, a disruptive projectile, excellent edgeguards, quick movement)
4. Marth (+1 for threatening movement, strong edgeguards, ridiculous priority, notable recovery. Attacks are too laggy to break top 3)
5. Jigglypuff (-2. I personally think HBox's superior spacing contributes more to the positive perception of Jiggs than the character merits)
6. Peach (+0 Just keeps coming back with that recovery. Not the greatest priority everywhere, but good up-close pressure game and good camping)
7. C. Falcon (+0 glass cannon. If he gets his hit he has monster combos, but until then he has to camp a bit, and has a mediocre recovery)
8. Ice Climbers (+0 Sopo~18th or 19th, but until then one grab = one kill and good spacing options. Nana's an idiot)
9. Samus (+2 for tricky recovery, decent projectiles, fairly viable close-range defensive options)
10. Ganondorf (+0 Bad mobility, easy to combo, long but punishable recovery, but once he gets his hit it hurts and his dthrow is pretty useful)
11. Pikachu (+1, maybe it's just that I play with Axe, but Pika's got gimps, a great recovery, and above average mobility which I think put him above Doc
12. Dr. Mario (-3 for relatively poor priority and a lackluster recovery. He's not that much better than Mario IMO
)
13. Mario (+0 Projectile, hitbox angles and knockback put him below Doc but walljumping, better combos, recovery, and fsmash range put him close)
14. Luigi (+0 WDs all over the place and combos decently, pretty free offstage)
15. Young Link (+2. Players like Armada and Axe have done a lot of innovating with this character. His mobility, ability to camp, and useful aerials make him better than low tier. If version 1.0 were tournament standard he miiiight be a step higher for the improved recovery)
16. Link (+0 Has his tricks, but his poor mobility and relatively laggy moves bring him down)
17. Donkey Kong (-2. Yes, he has juggling and a few quick moves, but he's a big target, lacks vertical recovery, and is generally predictable)
18. Mewtwo (+2 for recovery within blast zones, decent projectile, great WD and roll, somewhat ok spacing, powerful throws, better combos than Roy or Zelda)
19. Zelda (-1 Bad mobility and laggy moves. Fair and Bair though)
20. Roy (-1 for poor spacing, little combo ability outside of throws, and needing hard reads to kill many characters)
21. Mr. Game and Watch (+1 for high recovery, relatively useful aerials and the dtilt. Shield sucks and mobility is meh)
22. Yoshi (-1 for no OoS game, no 3rd jump, relatively poor spacing options. Surprisingly good at surviving but can't do much with its lives)
23. Ness (+0 vaguely ok low-tier neutral game but horribly gimpable recovery)
24. Bowser (+0 most combo-able, laggy character in the game with worst mobility. Up-B and ftilt are his only viable moves)
25. Kirby (+0 Lack of priority, poor horizontal and vertical mobility, predictable recovery, no viable projectile)
26. Pichu (+0 Lack of priority, damages self, more laggy recovery than Pikachu, does very little damage and can't combo)
