Tatsu, rori dropped the PR instinct bit after the first or second episode, after fan complaints and used facade, as every other group. Will probably be fixed in final batch (hope those doing the Blu-rays won't fuck that up).
EveYuu didn't really impress me. Had a lot of grammar issues, and I think at some times, I couldn't make heads or tails of what was said.
Commie is only good if all other groups suck, or if no one else does it.
gg is a good second choice. They've kept their trolling down for quite some time and a did solid releases every week.
