I've been making some custom maps for both Osmand and Comaps. The main big positive for Comaps I've seen is Android Auto being available freely (but you have osmand+ so moot point). But having used both, the tooling for osmand is far more mature. Creating an obf file (osmand file type) is a lot easier than the process for an mwm file (comaps file type). Far more routing or ui customization options in osmand and routing.xml files for even more advanced custom time penalties/weighting profiles.

I happily own a car with nothing fancier than a bluetooth radio. No touch screens and no Android Auto is a blessing.

But from this and sibling comments it seems that CoMaps have nothing to offer me (except possibly better search).
