So far my best are Link (from lots of use out of melee transfers over to this), olimar, DeDeDe, and Marth (though I hate using marth, he just feels cheap to me). I was good with Sheik in melee, but I've barely used her in brawl. I've been loving triple D and olimar too much.
Honestly I've been practicing with those two more than anything else, so I barely know about any other characters.
You can find me on facebook as Markus Van Rijn, if you friend me just mention you're from VGchartz and who you are here.
