I've bounced all around but have really liked OnX lately. I think I probably have 4-5 different ones on my phone now, but always end up using OnX the most by far. They seem to have the best mapping, best land ownership, public access and best hunting related app with features that are seriously helpful. In my mind, they are the current gold standard. Once competition entered a couple years ago they seem to really have upped their game.
As mentioned, they go on sale or have codes all the time, don't pay full price.
