peerfly

I have been reading about these 2 affiliate networks and have been considering using one of them to help make some more money. I do not know much about these and they both seem good but I would like to start with just 1 at first. Which one of these would you recommend to start using first?

I have never used Peerfly before in my affiliate marketing and promotions but have read a little about it and was wondering if Peerfly is any good for affiliate marketing of not. Has anyone used Peerfly or have any good knowledge on it? Is Peerfly good?
