To each their own, but I totally prefer the function of the Denali's Push-Pull PRNDL switches to those in the other trims. Yes, it is the same switch set, but the angle at which it is installed in the non-Denali is a non-starter for me. Perhaps I could get used to it, but the Denali's is almost perpendicular to the floor of the vehicle, where the other trims have it at about a 60 degree angle to the floor...making the P and R a further reach than the L button, by quite a bit. This alone, for me makes the Denali dash better.
As a person taller in stature, I actually prefer the HVAC vents up higher.
And, I prefer having covers over the storage bin (with the wireless charger) and cupholders to hide things in there if/when I park.
I am not one to love the recent fad of the top edge of an iPad sticking up higher on my dash than anything else...up there in the breeze...like it was an afterthought, but this is personal preference. Perhaps, because the bulk of the info I need from the infotainment system is in the HUD, including turn by turn navigation advice, and the audio stuff too (and in the IPC), I am in less of a need to look at that screen, so I don't mind it's slightly lower placement or see it as a functional impediment.
So, be all that as it may, I also like strawberry ice cream...so maybe I am in the minority, but I cannot impune the Denali's dash function. And I definitely think it's form is much more pleasing to the eye.
But, its all good, because GM gave us all a choice, you can get a Caddy, or a High Country and have many of the same amenities in a different form.
