I download almost everything using Premiumize. It essentially downloads the torrents for you, so you're only downloading things from them at drastically faster speeds, and never connecting to the actual swarm. You just send them the torrent file.
For the actual organizing, I use TVRenamer mainly. It's an extremely underrated tool that not only organizes your shows and movies, but does a great job of helping you identify what you're missing, like missing episodes or specials.
I use tdarr to reencode all my stuff to x265
Plex is mainly how I watch stuff. I like kodi a lot, but most the time Plex is a lot more streamline.
For comics I use comicrack. Best way to do comic organizing by far
Yes I have. The issue is it doesn't have very good built in scrapers. Comicrack has amazing tools for organizing your library, where Komga breaks really easy. Especially with series that have either long names or names that repeat, such as having multiple runs with the same name (such as Spider-Man). It wish was really really bad at being clear on how/what it was updating. In the end, I only read off one device, and comicrack did it better
I was trying Kavita in docker and the idle usage was too significant, I haven't tested for long enough but Komga has been about the same for me in metadata pulls, but I will need to test it out for longer.
That being said I couldn't find a non-canary build in docker for kavita.
