Explorer wins for me because it’s a backup GPS navigation unit and I’ve learned to not bet the farm on a phone / phone battery. I prefer double redundancy: phone + Garmin + map/compass
SameExplorer+ for me for the same reasons as above. The mini is nice, but if your phone battery dies, or you break it on a rock, your down to just the preset S.O.S. messages.
It’s only a few ounces more, but the added functionality is worth it in my opinion.
