3rd is for when you are really hauling and 1st is for when you are carrying a lot of stuff.
Ideally that means that you spend most of your time in 1:1 mode which I would assume puts the least wear on the hub
I may be remembering this wrong, but I seem to recall reading that 3rd gear is the 1:1 gear on this hub. On most three-speeds, that happens in 2nd gear.
