Don't know why people are so salty about PM in this thread. It's easily the best Smash game besides Melee. It has also had a larger following than people seem to give it credit to. I run into people fairly often that never played Melee, don't care about Smash 4 and love PM.
Usually they were Brawl players that just checked it out one day because of the competitive scene, then they never went back to Vanilla Brawl.
Now a days certain regions still play it as their top Smash game. New Mexico is one of those regions. Arizona was another strong PM region until Smash 4 came out. Then PM players that joined from Brawl split into two groups, those that play Smash 4 now and those that play Melee. So the PM scene here seems to be dying.
Unfortunately the ban from Twitch is what's causing PM's death. Not the quality of the game. The game is great.
I get some people didn't appreciate the fans stepping in where Brawl failed, but to claim that Brawl is any where close to PM's level is silly. To put it in perspective the PM scene is still bigger than 64 even though PM doesn't really get any major events.
Competitively I imagine people will still be playing PM for another few years, where as Brawl is basically completely extinct.
Also, PM gave Charizard Seismic Toss before Nintendo did it in Smash 4. The first time I saw that, it was sick. I also appreciate all the little touches they did with the characters like Samus's ability to have a Fire blaster or an Ice blaster and giving her two different A button movesets.
