What you think it is. Be specific please. I am looking at going with Garmin. Not sure which one, but not set if someone can give a compelling argument for another company.
My next one with be a DeLorme (PN-60 or whatever the top end model is when I have the scratch) for the following main reasons:
1. their InReach device
2. personal GIS like interface that is affordable
3. #2 allows for a lot of free map info from state/fed agencies
4. Ability to download imagery in the field if I needed/wanted to.
