Which ads service is better to choose for a game project?

Question

Java

There is a game application for android (java + libgdx). Tell me who has experience with ads. It is necessary that the ads allow me to draw ads myself in the place that I myself determine, and process the clicks myself.
1. Which service is better to choose (for a number of reasons, admob is not suitable at this stage)? To have a guaranteed profit, and not have big hemorrhoids when integrating it into the application.
2. What is better to work with? With a mediator, or with a separate service?
3. Territorial coverage Europe, USA, China.
PS Tried appodeal. They don't have direct support for libgdx. When embedding the sdk, the compilation time on my machine is 8-15 minutes (multidex on), debugging with such a compilation time is not real. Although it is possible that I am doing something wrong with appodeal.

Answer 1

well, at this stage, only admob is good!. because android is google, and admob is google and googleplay is google. and with admob google it will be guaranteed to show your game higher in googleplay than without admob..
