It's a tough question for me, it depends on the artist, the subject, and the animal they're changing into. If it's a feline, I like it anthro mostly, if it's reptile I like it full tf. K-9 is a mixed bag. Anyways, I voted the 3rd option. I never understood inanimate, I just don't like it, same for spontaneous pregnancy and birth. Now that really grosses me out xD.

I just like the classic tf, girl/guy changing into an animal, if it's a little or a lot I like it either way. I can be pleased with just hands turning into paws and that's it, if the artist does it well. I'm happy.

As for sex, it depends, sometimes it's done extremely well, others... Not so great. I completely accept sex in a tf, but it has to be done right. And that's an even trickier subject to tackle.
