I've never tried gatorskins, so can't speak on its part.
But Vittoria Randonneurs last forever for my kind of skidding. I'm not brakeless skidding all the time, but I do a decent amount whenever I feel trippy.
Anyway, I've used them for a few weeks and there is not a single noticeable sign of wear.
Rando:
+ they last sooo long, even more than your orgasms
-they are heavy-ass, obese mother****ers, they literally weigh a ton

I say, if you plan on skidding and tricking, Randos are the way to go, but really, considering them speed and performance wise, stay the **** away.
And I hear the gators last and are overall pretty well-performing (if you're not skidding a lot)
