Don't over-think it. Buy the truck with the best condition and best maintenance history, at the best price you can afford. Frankly, I think all this stuff about horsepower, air pumps, navigation, and so on is mostly just internet masturbation. Those things will affect your ownership experience far less than finding a truck that hasn't been neglected or abused. All years of GX are good. Mark Levinson isn't high end but it isn't bad, and they don't go bad often. Nav is truly terrible, but who doesn't have nav on their phone these days?
KDSS may be the exception though. It can be wonderful, but you have to decide if you really want or need it.
You're welcome to drive my truck if you want to compare between years and options.
