I use windows, OS X and Ubuntu on a daily basis.<p>And IMO Unity is the better DE. 
But I wouldn&#x27;t say Ubuntu is the better overall UX. 
OS X has my least favorite DE. But I think it has the better overall experience. I&#x27;ve been using OS X for about 2 years now and I can&#x27;t remember a time it came out with stuff for me to solve.<p>On Ubuntu recently I had to change the default kernel it was using and recompile my graphic drivers after an update, not that hard a task but not something an end user should have to go through. I&#x27;ve used Ubuntu 12 and am now using the 14 and it really has improved a lot both on reliability and UX, but it may take a lot of work to get it to be reliable depending on your hardware.<p>My dream DE would be something like DWM but without the tiling stuff, more features included out of the box and written in a higher level language.
