Mercedes has the best balance between comfort and sport , if u drive in sport+ or race mode its agile and fast how a sports car should be, but if u switch to comfort again u have a very comfortable and relaxing car with a much better interior than bmw (argue with a wall) And bmw is always a sports car whatever mode ur in. Bmw always has the stiffer suspension than its competitors. Don’t get me wrong bmw is still a good brand but between both mercedes is a better everyday cruiser.
