I really wanted the AT4. I love the look of it. I drove them both back-to-back and fell in love with the way the Denali felt. Both of them were fully loaded amazing trucks. The smooth ride and the power sidesteps on the Denali are fantastic. I went home and waffled back and forth between the 2. I loved the look of the AT4 but, I was leaning more towards the comfort of the Denali. In the end, I saw a video of a satin steel 4" BDS lifted Denali and decided that could be a possibility if I wanted. So, I bought the Denali. I like it so much that now I am trying to decide if I want to mess with the lift. I'm afraid it will mess up the ride quality. Only one way to find out, I guess.
