I can comment on my 2017 F350 Platinum as having very comfortable seats, same can be said about the wife's 2021 Expedition - both have the massaging function and during longer drives i really enjoy it.
I've rented several Suburban and Yukon's over the past few years for fly in family winter vacations and I find them to be very comfortable as well but the bottom cushion length is on the short side and after a few hours i need to get out and walk around a little bit (i'm 6-2, 215 so a bigger guy).
The only Ram product I've driven in for any real distance was a customers 2020 Ram 1500 Limited and i found it comparable to my F350 seat wise.
