I have a 2020 S560 (W222) with MBC and love it. It works on rough city/country roads as well as rough freeways. I love watching the car in front of my move up and down aggressively when they hit a bump and my car barely moves when I go over the same bump(s) seconds later. The only down side to MBC is that it doesn't work well at night since it apparently "Cannot" see the bumps. I'm hoping the W223 refresh will have a better system than the current W223 since this is one of the major reasons I haven't upgraded.
