It's the original Brawl, the original game is played competitively much more than any modified version of Brawl, the stages and music were modified and nothing else.
Coontail and Keitaro are the worst commentators for anything I've ever heard. If this is the best the Brawl community has, I feel sorry for them. Such annoying voices/mannerisms, I can't even watch this entire set because they bother me so much
