I have been trying to answer myself that question for a week already. This is what I do.
Check on your Adsense Account, go to "Advanced Reports">"Ad Networks" and you will see All the Ad Technologies providers that your app has gotten Ads from, that should give you an idea of which Ad providers would be good for you.
If your app is new and don't have any data, I would suggest to go only with Google(default).
In my particular case, my app has been up for 8 months with 450 installs and 45 active installs.
Google Networks reports a 91.5% on impresions and 97.3% on Estimated Earnings.
IMO having Google as only one provider will look better when the user wants to see who the app shares information with, instead of having a list of 12 of which never heard of. In the beginning I thought on choosing the best 12, but by the numbers it doesn't make much of a sense and chose to stick with Google alone.
DISCLAIMER: I know nothing regarding Ad Networks and I choose Google because of my Admob history and nothing else.

In compliance of the GDPR, Google says that I must 'Select ad technology providers' and get users' consent. But the Google-rendered consent form is not supported if any of the publisher IDs use the commonly used set of ad technology providers. This means that I need to manually choose ad technology providers for my account in order to avoid collecting consent myself with the 'with the Publisher-managed consent collection option'. Here I am blank.
Which ones should I choose, and what difference does it make if I don't use mediation and only use admob? Should I use only one provider i.e. Google?
Edit: Thanks for the downvotes. I honestly don't see why this is not a valid question, except that perhaps this should have been asked somewhere else, for which I seek guidance.
