My 2 cents. Video playback has always been an issue for me on linux, either tearing or stuttering. I have really struggled to get a distro / kernel / desktop / driver / app combo which runs smoothly on all my video files.
I have got 17.3 to as good as i can and am sticking with it. I have a spare hard disk which i popped in to try LM 18.0 and suffered from the dissappearing mouse pointer bug (since fixed i think) and then saw another bug which I only get with 17.3 and kernel 4.4+ or 18.0 with whatever kernel it comes with. To completely avoid the bug, i am on the 3.13 kernel series and 17.3.

Its a frustrating experience, as I am stuck on the old (but more stable) software base of Ubuntu 14.04 and would really like to get on the newer base. I have a printer which I cant connect to without upgrading and there are newer apps of all kinds in the 16.04 base. I have toyed with the idea of switching to Korora 25 with Cinnamon, but that only has support for 12 months and I am nervous about having to make a big switch again so soon. It took ages to iron out all the bugs with Mint 17.x and I am loathed to have to do it all over again! (I am talking about getting the user accounts set properly, fixing issues with the power settings, finding workarounds for the dock disappearing and setting up all the apps I use)
I dont feel like I am a power user with unusual requirements. Good video and non-tearing windows should be a given with any OS, IMHO.
