TIL there has been some drama about Organic Maps, what is the difference between OM and CoMaps?

Left from Maps.me to OM because of drama and intrusive features, do I need to leave OM for CM?

edit: seems CM shouldnt have that annoying gift icon

edit 2: CoMaps doesn't display (colored) hiking trails, so completely useless compared to Organic Maps, also can't even display tram lines after tapping on tram stop in Prague
