Ive used both Adscend and Adwork. If you are strictly using the cpa network as a content locker, I would recommend Adwork over Adscend as Adwork has many more incentive offers and a customizable locker page. Adscend is just a basic white box with 5 offers. With Adwork, you choose your theme, which offers to display, how many offers to display, ect.
For new people, Adscend Media is a great way to start because of their easily converting offers. I have tested both the adscend and adwork, but the Adscend Media is way better than adwork media.We have all of those options also.
Adwork is good, although they are quite hairy (shave alot).
adworkmedia , its easy to get approved but they shave a little
i tried both i advise you go with adworkmedia better offers for content locking and less shaving .
