Drove mine for the first time today, and if it wasn't for the low profile tires it'd probably be a very nice ride.
Too early to tell, really, but it felt slightly smoother than my Challenger. Which could be because of the extra weight.
I purchased the TH to replace my 18 SS. I needed more room. (Carseats, and buisness equipment). The ride is smoother than the Camaro by far, while retaining the steering and suspension performace you would expect. I am probably biased, because my work truck is a power wagon. They are not comfortable at all. On the other side, my wife was not impressed with the ride quality of the TH, but that's because she is used to her Escalade. No comparison! So, really its relative to what you are used to. To me it is perfect balance between performace and comfort.
