Adsterra Option Wanted

Recently I quit displaying Adsterra ads on my websites...
For many reasons...
I will create another thread on that.
But, I am now seeking another CPM network.
One that pays good and has good, honest, polite and fast customer support.
Can anyone suggest any?
Note, if you don't know about CPM networks, kindly don't post here to increase your post count.

Thanks WordPress ...
