Affiliates should have been contemplating this for a long time already (years), not just now
Generally, products like Cams and Sex Toys, if the site is long-standing and hasn't earned any reputation for shady billing practices, you want to be on Revshare with those.
Until a few years back I would have said the same about dating, but with the rampant fake activity, you are probably better off with PPS for almost all of them.
As for paysites, if it is a micro-niche or very niche site from a company who updates frequently and isn't known for problems, you can consider Revshare. Anything else, PPS.
Another thought I never see mentioned much is, say you push a site that would make you slightly less on PPS as it does on Revshare, but the Revshare takes 4 months. If you received the money in Month 1, re-invested it in your business(traffic, advertising, scaling, whatever) - would you be able to turn it into more money by Month 4 than the difference?
