i personally give it to mango, but i think it's between armada, mango and M2K

Leffen is really good as well though
He has constant ******** and is a douche , but at his best he can easily beat almost everyone else (with armada mango and m2k being the biggest contestants)
Though if you would let them compete in an all character iron man, mango would win simply because he plays so many different characters all the time while armada is pretty much only peach, m2k almost only sheik and marth and leffen almost only fox
Oh and if >>#9 is considered, Hungrybox plays almost only jiggles so yeah

i did see a video of mango and M2K doing the iron man and M2K won with like 10 characters left. although idk how much mango was actually trying. and yea i don't like him but i give props to leffen because he is really good

HBOX for life

Mango's been placing really poorly recently, he's falling out of grace as of recent, but I bet it's only temporary. M2K is looking pretty solid right now, and Armada's had a real big slew of tournament wins this year, but more recently lost to Hungrybox at Dreamhack a few days ago

I'd still give my vote to Armada. There are a lot of top players who can stand up to him... Hungrybox is a solid example. But here's one way I've heard it put.
Ever heard people call Hbox Angrybox? When he's kicking ass?
Well, Armada shows up to every tourney Armada goes to.
But Angrybox doesn't show up to every tourney Hungrybox goes to.
Armada is, simply put, a more consistent player. Which is key for being the best.
