Best Ad Provider available

Hello everyone,
There are lots of monetization tools available in kodular but which is the best among all those
By best i mean that high paying and good support.
I think so FaceBook Or Amazon any one from these

Every network have something special
Admob targeting is low but gives high CPC sometimes but user generates awesome revenue

There is no answer for that.
I think normally admob will be the best solution, but this will change a lot according to your app, the country of your users, the format of ads, (ex: banners pay a lot less the interstitial), etc.

yes admob is best ad provider
