Best ad networks for banners? (Except ADMOB)

Can someone please suggest a decent ad network for banners? I currently use StartApp and apparently they s*ck. Can’t use AdMob because of banned account.
Thank you.

Fan, amazon but both got low fillrates.
The rest suck badly in many ways. Mmedia gives 0.01 ecpm for 2 yrs now, airpush is shady, appodeal requires admob, phunware got really low fillrates.

If you can go native instead? Appnext is great.

Ok I tried to implement AppNext. It never shows ads despite I call them:

interstitial_Ad.loadAd();
if (interstitial_Ad.isAdLoaded()){
interstitial_Ad.showAd();
}else{
}

wtf?

I will play with appnext a bit today but if anyone has had similar problem I would appreciate advice

EDIT: I RESOLVED THE PROBLEM THANKS

which pay better at appnext native ads or interestials?

So banner ads nowadays are pretty useless? It’s all about Interestials and sh*t?

Try Facebook banner ad.

No idea, but both pay well and with good fillrate.
I use appnext for a More Apps button only - opens a webview, suggests apps. I had tried video interstitials too but too low traffic app to see any income.
My reply is more like from what I have heard and what I have seen from my own webview implementation.
