Not according to my experience with a top-spec Dell XPS "developer edition" with Ubuntu pre-installed about 2 years ago. Not only did I have intermittant Wifi connection drops but I was never able to get multi-monitor mixed DPI to work at all with or without Wayland. Even closing the lid/entering sleep mode was broken - the battery would continue to be drained (at about half the rate of non-sleep mode but still unusable).
