Keep away from Monumetric. In first message to me they required admin access to my site, after that I wanted to delete my account, till this day they don't respond to this request. But are sending me additional reminders to link my account with Google Analytics. :)
Just to note that while they don't use adsense, these platforms will also probably show the majority of ads via Google's network. So it doesn't really circumvent Google's power in this space.
I'm only familiar with AdThrive and MediaVine, and certainly it depends on the niche, but most folks make significantly more. I know someone who jumped 5x when they switched. Just a heads up though, the requirements are higher: AdThrive requires 100,000 monthly views and MediaVine requires 25,000 sessions.
Adthrive and Mediavine promise more revenue per page, and do achieve it, but mainly by putting more ads on the page, and then refreshing them after a set period of time. A typical Mediavine page might have 5+ ads on it.
