Streaming requires constant internet access, a platform that is operational, and they often have a limited library. I can download all the movies and shows I want and go out to sea, in the desert, watch while the power is out, whatever. Having a library built over the years that has anything I want as soon as it's released and I download it. I also use Plex so it functions similar to Netflix or Hulu except it's free and you have to download your shows/movies ahead of time.
To be honest, I mostly torrent music and new releases. Most of what's on TV at my house is Netflix which is paid for (mostly) by T-Mobile.
To each their own. I tried the sideloaded Firestick with Kodi and it was too much to keep up with and not worth the stress of getting shit from my ISP. My laptop has a VPN and while it is possible to hook up your router to a VPN it just isn't worth it to me. Maybe shit has changed since I fucked with streaming, though. That app may be awesome. Just sharing my personal thoughts and experience. YMMV.
