I love Calibre. All I do is maintain my library on it, and a few extra Kobo things like backing up the database. There's more I could use it for, but don't really need to. Mostly I read books. Calibre helps tell me what I have or don't have. The UI is fine. Updating is fine. It's free, well-supported, and in my experience works fine on my M1 Mac (and it worked fine on Windows last time I used it as well. I've never installed or used it on a Linux machine).
