this looks like fun so imma give it a shot
armada = #1
he used to have quite a bit of trouble vs falcon and puff i think but he stepped it up like a boss and he's won the last 2 ultra huge tourneys pretty damn decisively. iirc, he didn't drop more than a handful of games total at apex and beat hbox, mango, pp, shroomed, etc
hbox = #2
took 2nd at apex where he beat mango, javi (who is hella impressive), kirbykaze (who put him in losers), wobbles, shroomed, zhu and a bunch of other notable names. he finally took a set off armada's yl (as far as i know the score is 3-1 in sets now)
mango = #3
despite not having played since rom 4 (i think i read that somewhere, not sure if it's true but i wouldn't be surprised if it was) he did all sorts of awesome stuff at apex. ice, kirbykaze, javi in that exhibition match thing, lovage, etc he wasn't able to repeat his performance vs hbox from genesis 2 though and he couldn't climb over the mountain that is armada
dr pp = #4
i totally called him getting sick at apex. if he wasn't cursed with that whole get-sick-only-at-tournaments thing then maybe he'd be higher on the list. but he's cursed so he's stuck at #4
mew2king = #5
despite dropping out of the melee singles bracket thing and losing his controller mid-tourney he still took #1 in teams with armada and i don't think anyone would deny that m2k is insanely good at this game. the only people he ever loses to (besides wobbles loololololl) are the ones above him on this list
below these guys i'm not too sure who i'd put where
but for 6th/7th place a couple of names i'd consider are shroomed and wobbles
wobbles beat darc, unknown, and m2k and was knocked out of the tourney by pp and hbox. dude is hella good
shroomed had to play against teczero (sheik/marth iirc), i.b. (marth i think), kdj (went marth/sheik i think), unknown522, armada and hbox. that's a pretty tough bracket for a doc as far as i can tell. he only lost to armada (who he took a match off of iirc) and hbox, who went on to take the top 2 spots in the tourney.
there were plenty of other folks who performed hella good and i'd say are top 10 like kk, javi, hax, zhu, etc but imo they'd have to take the 8-10 spots
having written all this crap i can totally see why people write these all the time, it's pretty entertaining.
