Different networks work for different things honestly. Copeac has naughty or nice which is great for dating. Advaliant has UltraLean which is a great green tea offer. We have Acai Berry - Oprah which is a great acai offer. Really depends on what your'e looking for as well as who you trust. I say use a bunch of networks, split test your traffic to the same offers on multiple networks as shaving is pretty prevelent. The more people I talk with the more I find out when they split test their traffic vs. the networks they're currently running they find large fluctuations in the conversions rates due to tracking issues or shaving.
So split test and signup to them all. Then decide
1. who's not stealing from you.
2. who you like working with and trust.
3. who has the best offers for what you're looking for.
Sorry there is no cut and dry answer to this. But the more you know the more you know
