That's a very interesting question, and there are a lot of interesting viewpoints in this thread.
Personally, I go for the strong PPS sponsors over the revshares in most cases. I was burned pretty badly when busty-amateurs closed shop, and burned a few times since when a processor/sponsor went bust. In today's processing climate, I would rather take the sure money than risk losing rebills down the line (kind of like taking an early lottery payout at a reduced $)
My statsremote seems to indicate that for my personal traffic & choices, the PPS gives me a much better return that revshare overall.
That being said, my best sponsor seems to be a revshare that only pays me $6.23 per sale/rebill, but the rebills go on forever. And in a related note, I am still getting rebills on premium avs sales that I made years ago (a few hundred dollars per sale in those cases).
But overall, I agree that you need to make the decision on a site by site basis.
