We looked at both. RST has a little interior difference but after having a few Z71’s in my life, and 2020 Silverado z71 for the last year- it helped make our choice. We love the look of the Z71. It’s got the tow hooks and in my opinion looks better. I like that it looks a little more aggressive so if you want the more aggressive look, the choice is clear. If you like that Denali look, probably RST.
The Escalade looks awesome. Crazy that they are $100k. Good luck in your decision.
