This right here ^^^^^.
I have had a diesel since 2005, my last one was a 2018 L5P, nothing but problems, Ordered a 2024 AT4 2500 6.6 Gasser in April of 2023. Picked it up in June 2023 and love it!
I have almsot 20k miles on it and I have had it a little over a year.
The dealer even said most people don't need the diesel and he could take me out back to show me all the new diesels in for issues and repairs.
Going this route simplified a lot of things.
In fact this tows just like my 2004.5 LLY Duramax..which was plenty for my needs. New truck has 90 more HP and only 46 ft/lb less of torque than that diesel.
If you don't need to tow the earth to another solar system or are not towing 20k regularly, this package is great!
Did a round trip to Vegas and back got exactly 18.0 MPG for the whole trip averaging 68 mph. Towing I am 9-10 mpg. Around town 12-15, to work 15-17, straight fwy 16-19.
