Do it and don't look back. I got Gaia in 2012 and never left. I also used to make my own maps in geoPDF and run Avenza, as most of this data is totally free and back in those days none of the smartphone apps had the kind of data you could download from agency GIS data portals. But now, for $40/yr I'll just pay for it all and then also get the private land layers.For years I built my own maps in GIS software and used them in Avenza. A couple years ago I went to the Dark Side ( OnX ) out of ease of use. It's a good product in its functionality but Jesus the symbology sucks. I mean really, the roads and stuff, the way the ownership and BMA polys and their fills don't fade out with zoomed in scale dependency. I am often struggling to discern what I am looking at. I don't find it intuitive.
I'll be looking into Gaia. I'm always looking for an excuse to abandon OnX.
