I only use google maps to find bussinesses. It’s pretty awful for navigating, which is kind of what maps are made for.

I’ll plug Mapy.cz here. I’ve been using it for about 7 years now. It has even the most obscure paths that you wouldn’t believe would be on a map (at least in Europe) and the bussiness search is alright.

No idea if it’s based on OSM or is its own thing, but if I were to guess, it is.
