IMO:
Characters that should go down: Sheik (one group), Diddy (one group), Zelda (one group), Game and Watch (one group)
Characters that should go up: Ike (one group), Peach (one or two groups), DDD (one group), Snake (at LEAST two groups), MK (one group), Jigglypuff (one group), Ivysaur (one group), Pikachu/Link/DK (one group)
Characters that should be removed: Sheilda
-----
Top: Fox, Falco, Lucario, Wolf, Roy
High: Samus, TL, ROB, Sheik, Yoshi, Ike, Snake, Peach, Falcon
U. Mid: Diddy, Mario, ZSS, Mewtwo, Marth, Wario, Sonic, DDD, MK, Lucas, Luigi
L. Mid: GnW, Charizard, Ness, Ganondorf, Kirby, Link, Pikachu, Pit, Jigglypuff, DK, Ivysaur, Zelda
Low: Squirtle, Bowser
Need Fixed: Ice Climbers, Olimar
I think Squirtle and Bowser (and Squirtle is probably better than I think) are a few degrees of separation from being so ****ing obnoxious AND really good. Olimar... well. Ice Climbers when fixed might be between L. Mid and U. Mid. Not sure. Fumbles has shown me some really cool **** and I continue to be impressed by the character when they do things that look like they work or should work. Hylian is also really really good.
