IMO, most users will ignore it if it's not on Play store, they have never heard of side-loading or F-Droid or alternative app stores and dealing with trying to get them to install an APK or otherwise, no thank you.
Boy am I glad I published my app before the 20 tester rule came in, and am slowly moving everything to a corporation to deal with having to make an address and phone number public -- this is primarily due to Apple and EU "trader" rules.
If you plan on making any real money, I would bite the bullet and go with org/corp.
