Easiest: So far, Ganondorf. He was already pretty easy in vBrawl, but he's having a hard time adjusting to the physics changes in B+. It's like playing a Heavy Brawl or Giant Brawl - the CPUs don't seem to notice that things are a little different, and try playing the same as they always did.
Hardest: Toon Link, maybe because I'm not used to him doing anything other than running and throwing projectiles at me.
