I drive a Tesla Model 3 everyday for work and never have any seat comfort issues. I have a 2019 Jeep Wrangler that is comfortable all day.
I’ve driven my 2018 F-150 platinum cross country from Colorado to DC and back without any road fatigue. It’s simply better in every way in terms of comfort and ergonomics and NVH.
I do like my GX for what it is, but I’ve owned over 50 cars in the past 25 years, most of them brand new, none less comfortable than the GX. My build is 6’, 190lbs, so not a super unusual size or anything.
Ha, I just sold my Cherokee to buy a GX. Once I get that and my wife promptly confiscates it, I was going to trade our '12 Suburban in for a 2015+f150. Looks like the jokes on her!
