With the exception of a different theme (out the box, which lasted about 10 seconds anyway) it feels exactly like Mint XFCE 16 (which is great).
Install was a breeze (I'd have been surprised if it wasn't these days), everything worked out the box, the ati open source driver with arandr works really well (on the 7750 at work and the 6950 at home) though there was some tearing when dragging windows on the 6950 (tried the usual suspects) so I installed the binary driver which took care of that.
All the software I use day to day installed with zero issues (vagrant, phpstorm, pycharm, oracle-java7, chromium, firefox etc).
I also upgraded by vagrant configs to Ubuntu server LTS 14.04 (it's nice not to have to monkey patch in newer versions of PHP and Postgres with a bootstrap.sh) also with no drama.
For me at least the days of "oh now, new release it's going to take 2 days to put everything back" are long gone, I'm back up and running in < 2 hours.
