PROAdult
1. PROAdult has simple rules, and their internal link list kicks ass for generating traffic.
2. It has been covered on their webmaster boards that the preview area rules apply primarily to the pages linked from their internal link list. Meaning you can make different front doors for your different types of promotion that needn't adhere.
3. I also find it the easiest sell, given the included sites in both their PROAdult program and PROAdult Quantum recurring program. My rebill cancellation rate is single digits per month--it retains.
4. Free hosting, and it is the easiest AVS signup and setup process I have seen.

new to the scene is
AdultsAllowed:
1. Similar to PROAdult in many ways and very easy to set up and get running.
2. Brand new, not overcrowded--got signups rather quickly.
3. Allows TGP on their free hosting--I don't know any other AVS that allows that.
