My deciding factor for the SLT was the option of a chrome bumper. With the Denali (and now the Elevation and All Terrain) they come with a painted front bumper. After 10 years with my '03 Tahoe Z71 and 3 years with my '13 Silverado LTZ, both with painted front and rear bumpers, the front got chipped up from rocks and therefore start to rust. I wasn't going to go thru that again. I know I could've gotten a clear bra or similar, but I didn't want to toss away another few hundred dollars. So I optioned up my SLT with everything that I wanted, which got it near what a Denali would have and I'm satisfied with my results.
