I think that there is lots of reasons most people prefer PPS, but I think 2 of the most common are:
1. They don't want to be "partnered" with a site, they would rather just sell the traffic or joins(however you look at it) and get a $35 or whatever PPS chunk of the action and be done. The reason being, situations like Busty Amateurs, where I know people that had tens of thousands in monthly reccuring and one day...BAM site was closed! Recurring gone, site gone, options to get paid gone... So when your in a parnership and you don't control the site, your on the short end of that "partnership".
2. Is they are greedy fucks like GG... lol
