Except I find OrganicMaps to have an even worse version of the problems of Google Maps for the exact reason you say it's good. I mostly don't care about all of the "interesting buildings". I care about the one interesting building that I'm trying to get to. Often, I literally cannot get it to show me the business I care about because it's the ground-floor coffee shop in a 10-story office building, and it would rather try to have 40 tiny pins for every legal firm and startup crammed onto the building than show me the ground-floor option that 95% of people would probably want.

I get it - they have no information about me. They maybe don't even have a way to understand or even guess which one I may care about, but in a city with any amount of density you need some fairly strong heuristics on what pins you're showing to filter out the valid businesses that you're unlikely to care about.
