I just traded in my 2019 Ram Laramie last month and bought a 2021 GMC Sierra 1500 Duramax with the SLT Premium Plus package which is comparable to a Ram Laramie or a Ford F-150 Lariat.
I bought the GMC for the engine and I really like the outside looks after adding stainless steel side moldings. As far as the interior is concerned, yes, Ram is a little more refined and/or plush. With that said, I have no regrets and really like the GMC, especially the engine/transmission combo.
