Quoted from finman2000:Roku has an interface that is easier to use than the firestick. Something to consider if your not tech savvy.
Ditto^^ I do like the Roku interface a lot better than the Firestick but I still use both.
You can side load Kodi on the Firestick, but I don't bother - too much to watch already.
I assume you have HDMI?
