I haven’t seen osm2gmaps mentioned yet. It by default only uses geo chords but you have the ability to add an api key for what3words that allows you to search addresses like you want.

I’ve never had a problem with magic earth, personally. They have a feature that allows users to report road closures, speed cameras, etc… What may be happening is that a user local to your area is falsely reporting things for one reason or another. Unfortunately, I’m not sure there is a whole lot to do about this. It might be worth contacting the company about it.
