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.
