Which Ad networks are performing better for banners?

Hi,

After Google policy update banner ads have recovered more value in our earnings. I used admob and airpush banners, but nowadays there are not good solutions for me.

I consider to risky using admob due to the last experiences from banned users, and my cpm from Airpush’s banners have splitted more than a half. Fill rate from Airpush have dropped too.

Which are your experiences with banners ads after the policy update?
