Ride quality- hard to tell and will probably vary from rim to rim. Spoke layout, Carbon layup…

I went from garbage stock wheels - heavy, shallow, bad hubs… to a decent, not top end, set of Roval 38mm deep. 3/4# lighter, faster in all situations. About 1/3-1/2 MPH faster on the flats at 20MPH. And gets better the faster you go, aero comes into play more. And the ride is better, less vibration and stiffer under acceleration.

Depends on how you ride as well. Speed, how strong or big you are. I can flex rims/often break spokes. The CF wheels are just better in that regard.

You have a better starting point than I did. The difference or noticeable difference may be less.
