Gaia is actually great, I like the hardcopy BRMB, and I carry 2-3 of them in my truck all the time depending on where we are/going.
But having all the books, and the ability to see exactly where you are on the map at all times, trip planning functions, etc. It really is a great app.
I haven't tried Onx (which all the youtubers are peddling now), I did briefly try Hema, but that wasn't what I was looking for.
