I have for the weekend, been toying with MINT 18 and I have found a number of things.
Firstly is that my screen rez is a bugger to get above 1024x768 without some trickery. I have managed it, but it wont stay after a restart, but then I have the same issues with Sabayon anyway.
Another is that ( unless I am utterly blind ) but I could not find a KDE distro, and so I grabbed the Cinnamon and installed KDE from that, and this ended up wrecking my install.
Not much of a problem... I have an SSD for root and Swap and my HD for /home and I never usually format /home but this time, what I have done, is took my normal /home drive out and I am installing to a brand new pair of Drives as I have done 2x60GB and 2x1TB in 2 RAID setups for a giggle, plus I am trying out UEFI ( not really worth the hassle IMO ) and after all the fannying about, I have decided that it might be a tad too early, or there is just too many hiccups for it to be worth a stable install and as of half an hour ago, I went back to 17.3 KDE and so far so good, its installed without UEFI but ont the dual RAID setup and its as quick as I can expect it to be.
