I would put it this way:
Teagan
is the best thing since sliced bread, in still photos. Nobody else comes close; she's cornered the market on cute. For now anyway.
However, she has been thus far an average performer. This has been discussed
here.
I'm not sure she's an attention whore per se. The Teagan Cult on ADT wasn't anything she started; she heard about it and joined later and understands it's a good thing to feed, etc. I haven't followed it recently but as of a month ago I thought she was following the thread and not pushing; no Brenda-style self-promotion but rather helping an obsession maintained by fans.
My guess is that Teagan is a rare case of a "virgin" entering porn. I suspect that most girls have done some stripping, hooking, or something, before doing porn. They have some practice working an audience, client, etc. At least they had boyfriends after leaving home. Teagan, on the other hand, may well have never done any sort of erotic job of any sort and every boyfriend may have been a highschooler. Her performance may well be what a porn director gets when the girl's most-worldly past partner was some pimply high-school boy scoring for his second or third time.
