I test rode the 2020 Domane (SL5 trim) and current Roubaix back to back on some rough and smooth roads near my LBS. The Domane is markedly smoother over rough surfaces, even the front end. I was expecting the Roubaix to be better at least in damping out front end vibration but that wasn't the case.
My wife was with me so we were swapping bikes back and forth. She had the exact same conclusion. The Roubaix is more agile, if that matters to you. But for comfortably chewing up the miles, the Domane was fantastic.
