you can use the basic stuff in basemap free of charge too.
I've spent many years in the software industry, and have talked w/ OnX in a professional capacity - they have made some "interesting" decisions (my opinion of course). I'd choose GoHunt and it's up and coming features over the others.
Basemap has gotten to the point they can do what On X does, but they got there in a fraction of the time and with a lot less people and choose to reflect that in their product costs it seems. Basemap are WA boys too, its a local grown product.
There are lots of GIS systems out there that are a lot more powerful than any of these, but you would have to roll your own hunt specific layers to take advantage of that, definitely not a convenience.
One thing to keep in mind with parcel data and up to datedness - all of these are totally reliant on records from county assessors - it's not uncommon for county records to not get updated in a timely manner, some counties are a little slower than others...
