Roku by a country mile, a friend of mine had a Fire Stick and it was the worst streaming device I've ever used. Laggy as hell, crashes very often (especially Emby app), no YouTube because of a petty squabble with Google and it's heavily geared towards selling Amazon media, other apps are an afterthought in the main menu.
I've got 4 Rokus now and never had an issue with any of them, they run smoothly and have a much simpler and user-friendly interface and the Emby app runs like a dream. I have, let's say slightly older, users on the Rokus and they can use them easily.
Only issue is I'm using Roku 2s and 3s, which they don't sell any more. The only Roku devices available now are f'ing streaming sticks with no Ethernet ports so WiFi only. Not happy with Roku for this decision, I bought two of my boxes used off eBay.
