I don't think you can judge a character by the way AI performs.
If that were the case, then Ganondorf would have been God Tier in Melee.

Agreed... although AI Ganondorf in Brawl is not as good.
I do a Smash League on my own where I agree to "coach" certain characters.
All characters are in the league and the league even has conferences.
You play a regular season of 11-13 games and play everyone in the Conference.
Then there is a 16 team tournament at the end. Seeds are decided by my rankings usually based on wins, quality of wins, strength of schedule, etc. (It is very much similar to College Sports and I am a big College Sports fan so this explains it). Ones I don't coach I watch them battle in AI match.
My Conference right now are (They change)
Mushroom Kingdom Conference
Mario
Dr. Mario (Had to keep him from Melee he had 11 Final Fours and 3 Championships so he is a Mario alt costume)
Yoshi
Bowser
Peach
Luigi
Wario
Donkey Kong
Diddy Kong
Hyrule Conference
Link
Ganondorf
Zelda
Y. Link (Toon Link)
Marth
Pit
Ike
Ice Climbers
Space Conference
Fox
Falco
Wolf
Captain Falcon
Olimer
Samus
ROB
Ness
Lucas
Pokemon Conference
Pikachu
Jigglypuff
Squirtle
Charizard
Ivysaur
Lucario
Dreamland Conferece (they play each team twice instead of once like the others)
Kirby
Mr. Game & Watch
King DeDeDe
Metaknight
Independents (not in Conference)
Sonic
Snake
So I get to see every characters AI. Falco and Ganon where dominate in Melee, in this one it seems that Snake, the Pokemon, and GW are all real good. Wolf is good as an AI.
Sonic was the worse AI going 0-11 in my first season as him, I took over to coach him in season 2 and went all the way to Championship game before losing to another team I was playing as (Fox).
In Sonic's third season, I led him to 9-2 record and number 1 seed but he lost in second round to Pokemon Conference Champion and 8 seeded Ivysaur.
