You’re not wrong but there are still drawbacks to Kodi where Jellyfin ends up being better. In my use case, with 5 tvs in the house, 2 are hooked up to Nvidia shield tvs but the other 3 are Chromecast w/ Google TV which have very limited storage unless I want to spend a fortune in hubs for each one to add a USB drive or micro SD.
With kodi installed I would regularly hit the storage limit of the device and have all kinds of weird bugs. Just as an example I had my daughter set up with a kids only account, but account switching would cause Kodi to become unresponsive for anywhere from 30 seconds to having to do a hard reset of the device. Jellyfin gives me the same access to my library with a lighter, more streamlined, persistent interface across devices and with easy and fast profiles. It still allows me to keep a pi as the host so the whole setup is low power (important for me as we’re on solar, every watt helps!)
I don’t really need the Kodi plugins I used to have if the main purpose of streaming my local content isn’t smooth and simple for the family. This is coming from a long time XBMC user, I’ve been running it since my original modded Xbox in the early 2000s.
It’s no tits? That sounds terrible
