Have had both. Onx interface is easier for first time. But giaa is way more powerful. Takes more time to use. It does everything onx offroad and hunt does, and way more. Planning a trip is much easier, as you can trace way larger parts of map easier and quicker. You also can also have multiple layers running at once which is helpful. If you are willing to take the time to learn it, giaa is a no brainer compared to onx
Ok, that's about what I was after. The main question was whether or not it was worth a bother to check out OnX when I'm already used to using GAIA. Maybe I'll try the paid version of GAIA to better enjoy using it. Anyone voting for OnX over GAIA, please chime in with your experience, I'm just curious.
