Yes, we pay net 15... but you shouldn't decide which network to work with based on how quickly they pay you. That's a very short-sighted approach.
If you really want to do well with a network, then I would think you should be more interested in the offers they have, the amount they pay per offer, the quality of the network, etc. As long as you get your payments in a good time frame, then that should be fine. I don't mind having mine monthly or even Net 45, as long as I get them. I'm more interested in a networks quality, support, etc.
