I spent two days trying to get Stable (Jessie) to work with Skylake before giving up. Meanwhile Stetch supports Skylake almost perfectly, and is quite stable for professional work; I've seen only one buggy package (ffmpeg), and it was easily rolled back, and ultimately fixed in just a couple weeks.

I do use Jessie with Broadwell, and it runs quite well indeed.

Gnome 3 is a full desktop environment with pretty good tiling functionality built in and enabled by default.
