the main issue aesthetically with air is that they can look funny sometimes. if you have perfect fitment when aired out, it can look odd at ride height, and vice versa.
I don't have the cash for air, and if I did I'd move to a different platform (and stay static lol)
edit: I do agree though. look at Dave, his rolling height is basically the same or lower as when he was static, but he parks on the ground. ReZpEkT.
