Help please ! What to choose betwen them ?

Hello peopple

I’ve make my 1rst app (a small game) But actually im earning nothink on it

and at the moment im front of a BIG MISTAKE

My choice about Ad would be more top banner (for the moment)

Im wondering wich is the best for banner betwen StartApp - Appnext -Mobilecore
and eventually Admob (admob not finding my app , i dont know why ) ?

If i could have some explaination about the best one, that would be great :smiley:
