What problems have you faced with organic maps? I have used it have a dozen times and had no problems. Does it not find the best path?
Organic maps is OK and will get you to where you need to be, but routing is odd. It’ll sit you in the worst traffic and doesn’t know about road closures etc.
Usually an Any app that knows traffic situation, knows it from your (and other users) location, so it obviously doesn’t know about traffic.
Edit: Magic Earth gets this data from a third party: https://lemm.ee/comment/1993667
In openstreetmap it’s not recommended to map temporary things, and the map only updates once a month in OrganicMaps, so that’s also expected.

If I remember correctly Magic Earth claims to get its traffic information from public sources, without using user’s locations like google. So no, location data is not strictly necessary for that.
