The main issue I've run into is having a high DPI 4k monitor as my primary display, and a 1920 x 1080 monitor as my secondary display. In the past, I've have been happy to tinker a bit to make it work, but these days I'm busy working, so I want my display setup to just work out of the box. Ubuntu is close, but 16.10 applies the scale factor from the 4k display to the secondary display as well, so things don't look very good on the secondary screen. It just works without fuss on Windows 10, so I tend to just run Win10, even though I prefer the look and feel of several different Linux desktop environments. The Win10 linux subsystem has been good enough so far than even ruby and rails development is painless - whereas before I used to run into some minor but annoying issues. My Linux desktop experience is far from terrible - these days, I just fire up a Win10 or Linux VM and full-screen it on my secondary display and just use it for running a browser to look up documentation and other such things. In doing things that way, I'll end up with proper DPI scaling on both screens. But it adds enough friction to the process that I usually won't bother with it until I get sick of the Windows look and feel and want to look at something different for a few days. I realize my use case is probably atypical, but it as least serves as an example of a non-seamless Linux desktop experience.
