Hey, Well make some distinctions, Megapush - Marketplace, they close deals and have tons of traffic. AdMAven/Propeller - Direct traffic from direct sites. I would suggest going for any of the direct traffic sources and go for the rest on smaller tests. Propeller for instance did really nice for me on Crypto, AdMaven kicked ass for me on Sweepstakes and Dating and some Crypto. In the end, always go for direct traffic!
