FTN, ScT, RevTT, TL, BlackCats and Xbox-Sky are the ones who regularly get new games as they come out.
I'd say the best are SCT/FTN, but as they're pretty hard to come by, BlackCats usually get them first of the other 4.
ISC - The Israeli elite.
yeah xbox sky has great content but the speed is ridiculous
blackcats still is the best choice for old release.
for new release, TL, REVTT are easy to get in and have pretty much everything new.
