I use both BaseMap & OnX, they’re both better than the other at certain things. Lately I’ve been using OnX a lot more because it’s easier to organize my information on the map- I can set my points to show a different picture & a different color for different activities, BaseMap makes you choose one or the other. The other huge thing for me is OnX has CarPlay. I’m primarily a bird hunted, so I can see posted land & available land on my stereo while I’m driving. That’s huge to me.
