Do you mean with native "adview (banner)"?
In my opinion interstitial ads are no longer a real reason for uninstalls. Today almost everyone uses intetstitial ads so people are used to it . If you find the right way how to show them so its not too much disturbing for the user then u should go for it.
Their is no doubt that interstitial ads generate much more revenue and if someone doesnot like them then he can purchase the no ads version.
Bottom line if u want to make money from your apps u should use interstitial ads BUT give the user the option to remove them via inapp purchase and also have a look at admob tutorial video how to do it right.
Good luck
