While I don't know enough about each character I do want to make a few comments on some characters:

- High mid tier at worst. Aside from two of his aerials suffering from high landing lag Captain Falcon is a very flexible character that has a lot of ways to adapt and react, he has so many great attacks that are just made for combos. There's nothing terrible about him either outside of the little landing lag issue, he's not great at recovering but not terrible either.

- Forget Brawldorf guys, he might look the same, but I assure that he isn't. Ganondorf has received notable buffs, and at the same time the game itself has shifted focus to favor him. Ganondorf's U-Air, B-Air, F-Tilt, D-Tilt and F-Smash have all received speed buffs and thus are his best attacks. At the same time he has received a lot of damage buffs too. That's just one thing though, cause the most important thing is that while everyone KOs people in the 100%-150% range in this game, Ganondorf can do it as early as 70%-90%. Ganondorf's knockback is ****ing ridiculous, his U-Smash KOd Wario at 74% in one of Shofu's videos, his F-Smash can KO everyone on the edge of FD at 80-90%. Punishing is more important than ever in this game, and Ganondorf is the best at that in the entire game. Still, he still has his speed problems, and his recovery is also still pretty lame, so while he's nowhere near as bad as Brawldorf he should be mid tier at least.

- Once people learn to properly predict his projectiles DHD is going to suffer a lot, his Down-B and Side-B are both rather slow and can both be broken, thus aren't going to be great tools once people can adapt to them. He's still a good character, but not top tier.

- This beast is underrated, Dedede is a top tier candidate. His D-Throw is a guaranteed combo setup, he has tons of range, he's got decent speed and a lot of power, and he has possibly the best and most unpredictable projectile in the game, the Gordo has infinite uses. People really need to open their eyes for this character.

- High tier, it's not really debatable. All of her aerials are godlike, Pound is a shield breaker, and you can combo into Rest or simply do it out of shield. I don't think she's top tier since she isn't quite up to her Melee power, but at least high tier.

- Mid tier incarnate, he's got a lot of good things but also notable drawbacks, at the moment I wouldn't put him anywhere else.

- Ike is the worst character in the game by a very long shot, and I absolutely hate to say that, but that's how it is. Everyone around him has been buffed while Ike has actually been nerfed, meanwhile they have not adapted him properly to the new game at all. He kills people at the terrible 110%-130%, no earlier than the likes of Mario who are much faster than him and much better at racking up percentages. At the same time his recovery is absolutely dreadful, with the ledge nerfs it's become harder for him to recover than ever, it's now much easier to gimp him or body-block his Side-B. Ike is a case of a character that seemingly wasn't prioritized very highly and thus has been left behind, it's clear that they have not put very much work into adapting him to the new game at all. I love Ike, I'm going to partially main him no matter what, but I can't deny how terrible he is. I saw someone bring up an excellent point, why play Ike instead of Bowser? There is no reason from a competitive standpoint, Bowser is better than Ike at everything.
Otherwise I don't have many unique things to say, Sheik is top tier, I'm not sure if Bowser is going to stay there but with the current "meta" he's definitely up there. People should wait quite some time before rating Rosalina, her meta is going to evolve a lot every week, both for the better and the worse.
