Carbon rims (prior to 2016 or so) were notorious for offering a poor braking experience and you ran the risk of overheating the brake surface on big descents and potentially delaminating the carbon rim. Better wheels and pads were manufactured, resulting in a much better experience when riding on higher quality wheels. No mistake, disc brakes offer better braking power and a superior braking experience to rim brakes but the difference is nowhere as big as it used to be.
