Fox, and no I didnt't play him in melee at all. (O SNAP, THIS GUYS A 1st!!! HE PREFERS NERFED FOX?!?!?!?!) And no. Fox isnt nerfed one bit if you ask me. Just different style.
I mained Samus the whole time in melee. In brawl I hate her. I know she doesn't suck, but I know she plays completely different, and I dont like it. As for fox. Ive always liked fox as a character. In addition, he fits my style: agressive, fast, and powerful. And if all else fails, you always have your blaster. I didnt like fox in melee because he falls like a rock. He still falls fast in brawl, but no where near as fast, and I love shine stall. It is an awesome defensive manuever. As for matchups, I have done very well with him. There have been only two matchups that I've constantly had problems with : Zelda and pikachu(the latter mainly cause of the freaking chaingrab).
I like Metaknight a lot as well as a main. Awesome aerial attacker. Great priority. Tornado.
Ridiculous recovery. Tornado. Quick attacks. Did I mention Tornado?
. Really though, I dont spam tornado, and MK fits my style as well.
