GPS downloads/features

[Naches Sportsman]

I have been out of sync keeping up with the latest technology and pulled the trigger on my first personal gps today. I have been exploring maps a little bit. And for sure want to test out the onXmaps since I heard high regards of their land ownership maps.  I am going to get the topo24k for basic use and have looked at the Garmin huntview, but is it worth it?

also, what downloads do you all have? I basically have all my stuff I need for working and just want to get decent downloads for hunting and personal use.

Thanks.
