What type of banner is batter to use: static or animated? With "real" women with more amateur look or "hentai" and "anime" sexy charakters?
To be honest you just have to test.
In general though I find animated works better than static just because of CTR. However that's not always the case (especially with mobile).
"Real Women" and amateur photos are better than magazine quality or super hot women.
Hentai and Anime can work, but in my experience it will be dependent on geo and what you are promoting.
Good luck.
There's no one single answer to this: you should test and see what works for your traffic source/offer/demographic combination.
Generally, real women will work better than cartoons (but there are exceptions and they can be very strong) and animation will get a higher CTR (but not necessarily conversion rate) than static. But you should always test in your specific case.
