Between Tube Archivist (TA) and Pinchflat (PF), it seems TA is a better choice (because you want to delete the downloaded videos). TA has a built-in interface to watch and delete the video. But if you are like me, who watches the videos in Jellyfin and don’t plan to delete them afterwards, then PF is a solid archival application.
Depends on the application really. For example, I don’t need to update Jellyfin and the arrs as soon as the new updates drop. They work just fine and I’m not waiting for any particular fixes.
