Upgraded. Love it. Had some issues with nVidia drivers and then FFXIV, but those are sorted now. (Will probably clean install this weekend, as I don't like leftovers from "upgrading.")
I've been using Win10 since September or so, and honestly I liked Windows 8/8.1 too. I've never understood why people always give the new WinOSes so much static when they come out; if they wanted everything to be the same, why bother upgrading? Anywho... The layout is different, but if you don't mind learning the interfact, I think you'll really like it. I'm slowing converting everyone in the office by showing them all the cool stuff I can do. (Enhanced window management, multi desktop, Cortana, Xbox One Streaming, etc.)
