Watched this video yesterday, guy drove 4 Silverado's that were pretty similarly equipped w/ all four of the offered engines 2.4L turbo 4 cyl, 5.3l V8, 3.0L DuraMax, and 6.2L V8.
Which Silverado Engine Is Best? Let's Find Out!
Is not very scientific, but interesting to see his reaction.
I had the 5.3 in my 2013 and never really complained; until I got the 6.2 in my 2022 Denali...lets just say its pretty fun.
Premium is the one thing I find a bit annoying, but fortunately, Costco is 0.5mi from where I work, so I just fill it up there...their premium usually runs about $0.20/gal more than the regular at the rest of the stations in town.
It's worth it for the smile factor for me...if Fuel Economy is your #1, get the Duramax. I know 2 guys who have Silverados, one with the 5.3, the other w/ the 6.2; their highway MPG's are about 0.75-1 MPG different; in town are almost identical.
I have gotten as high as 22MPG for a road trip if I keep it sane, if am on an interstate where the traffic is moving 75-80mph, its pretty steady at 18.x.
As for Escalade vs Denali vs Suburban...just do your homework...
I ended up on the Denali, as it was a bit more bang for the buck, without breaking the bank on the Escalade. Also, maybe ask your insurance agent about costs to insure each; Escalade was about 2x what the Denali is for me...your mileage may vary. Here is a motor trend article from 2021 saying the Denali is the "Value Play"
Does the price jump from Chevy Tahoe to GMC Yukon Denali make sense, or should you really spring for a Cadillac Escalade?

There is a thread on here where there was quite a discussion about the differences in the Suburban and the Yukon. There are definitely some hidden things in there that are not obvious. Ex: Fog Lights not on the Suburban, Suburban does not have laminated front door glass (quietness), interior differences, inclusion of 3 years of connected services on the GMC, 1 month on the chevy, etc...
