I just got my Enyaq 80x with DCC and 19" wheels, and I have to say the difference between sport and comfort is very subtle.
Speed bumps and other small bumps is indistinguishable between the modes, but longer bumps makes it feel more floaty in comfort, and it settles down a bit slower while in Sport it follows the road better and settles in quicker.
The difference seems to be more about how it behaves in corners rather than how it soaks up bumps. I like how it behaves in all modes but would have liked a bigger difference. Normal mode is perfectly fine however.
