Brawl-: before I tried this mod, I thought it would be too silly to be taken seriously.  I always hated the OP PSA's, seeing no point in them, and I sort of assumed minus would have a similar feel. Once I tried it out though... instead of seeing stupidly overpowered characters, I saw insanely unique playstyles.  Yeah, they buffed every character and gave them a gimmick, but the buff's and gimmicks are UNIQUE TO THEM, and it's surprisingly balanced. I've always felt that the main appeal of Melee was that everyone was broken in their own unique way. Brawl- does this, and it does it better. The mod also succeeds in making every move for each character practical, which is always a plus in my eyes. I think this is the ideal mod since it's extremely fun for casual players, while having an absurd amount of depth to it for competitive players (which was a surprise to me). Minus is hands down my favorite mod.

Brawl+: I liked this mod more than vBrawl and BBrawl when those were the only alternatives, but they were too conservative. I prefer the higher hitstun / lack of ability to cancel hitstun into moves / dodges, and I approve of the increased spead of the game, but it just isn't anything special. I still play it only to use solid PSA's (Geno, Zero, Metal Sonic, Athena, Megaman and Naruto)... since as far as I know, none of them have a minus version of these.

PM: It was what I looked forward to most and hoped for most, originally, but I honestly don't care anymore now that I've fallen in love with minus.  I will likely play this on occasion, and I do really appreciate that the clone engine might come out as a result of the mod.

BB: eh... I'm just no interested in a game that doesn't change how hitstun works... as this is probably the main reason I did not like vBrawl.
