Very good and much easier to setup than Kodi due to the add-ons being cloud based vs locally downloaded. I still recommend learning Kodi as a more reliable backup. The torrentio addon for Stremio goes down on occasion for a few hours which can happen at inconvenient times. Lately it's been pretty stable though.

Having both set up and synced with trakt is recommended.

Sorry for the reddit link but this is a great guide for Stremio. Beautiful thing is you can set it up on any device and all you have to do for any future device is sign in. All add-ons are cloud sources that save your settings to your account. https://www.reddit.com/r/StremioAddons/comments/15agu2p/stremio_torrentio_debrid_a_howto_guide/
