I've never particularly been a fan of stats in RPs, though since I do a lot of tabletop gaming lately, I guess I can see the draw of it. Still, multiplayer writing is already confusing enough with each person having their own motivations and schemes brewing, and stats can occasionally inhibit some of the best things I remember reading in RPs from happening, so, in my opinion, it's best to just kinda hang around with mature people who won't try to break the story with bigger, stronger, more magical characters, and working out how the fights are going to end if it looks like a stalemate is incoming.
Also statless RPs usually are easier to sign-up for, so I'm going to count that as a point in their favor.
