Roy is like the ideal character with easy to see strengths and weaknesses, but he can cover his weaknesses by just being a powerhouse.
Yoshi is also pretty good, especially once parrying is in, but it can already block grabs which is SUPER annoying.
I think Kirby's dash attack should require more investment because it is super free and near nonpunishable unless you know they are going to do it.
Snake is pretty balanced. He has strengths and weaknesses along with cool stuff.
Pikachu is lame so I guess balanced.
Ike seems pretty solid now, along with Zard, and ROB.
Falcon is fine from Melee, and Luigi isn't bad either.
I want to say Wolf is though he can do crazy stuff.
Oh, and Ness is pretty cool too.
Diddy shouldn't have 2 bananas, his recovery goes way too far.
Mewtwo's teleport is still too fast.
Metaknight is Metaknight....
Lucas has a plethora of KO options.
Mario's fireballs still too exploitable.
Spacies are hard to punish and have metric tons of pressure they can drop on you.
