Looks like Ore Twintail ni Narimasu 01 was pretty good. And:

This director also did OreImo, which I didn't watch (Eeew!) but a lot of people liked. It was popular enough to get a sequel.

Siscon is too much for me. I don't usually like switch hitters, either, but I think I can tolerate this one because I think they aren't going to dwell on it.

That's the crux of matter, isn't it? Still, Kampfer was quite good until they peed the story down their legs (well, the LN author did). I'm not going to do the same mistake and get invested into watching Twintails in-season, but godspeed.

UPDATE: I think Pony Canyon ought to strike a deal with Crypton about a guest appearance of the most famous Twintails of them all.

UPDATE: ANN says "Sumire Uesaka as Tail Red". Why not Tail Red Star? :disappointed_asian_father.jpg:
