This thread is is the Google Ads section, so I will mention my experience with anti-detect browsers in respect to using anti-detect browsers for Google Ads.
What I do is I use a mix of anti-detect browsers, with an equal amount of my Google Ads accounts spread over Multilogin, GoLogin, AdsPower, Kameleo and Incogniton. In my experience, using a mix of anti-detect browsers is the best way as far as Google Ads goes. And, remember, if any Google Ads account gets suspended, always appeal the suspension irrespective of whitehat or blackhat campaigns running in them.
