I went with the 3.0. There were a few reasons. 1 being i had been driving a 2019 with the 5.3 and really didn't care for it. it was also a 6 speed. This was a company work vehicle and we had about 6 of these. My engine was replaced under warranty(56,000 miles) as well as the tranny(15000 miles). A few of the other trucks in our fleet as well had the top ends rebuilt under warranty. Also it never felt smooth when shifting When it came time to buy myself a new vehicle it wasn't going to be the 5.3. January of 2022 found mine on the lot (no 6.2 available) and made a deal for $8k under MSRP. I couldn't turn down that for the 3.0.
