Used epubor ultimate from 2019 on and was quite happy with it. I had trouble after I mistakenly updated my Kindle PC version and though I tried everything epubor support told me, couldn't get it to work again even with a Kindle downgrade. After upgrading Windows from 7 to 10 it worked again and I was a very happy user again. It's really nice, not to worry about your books and it's so very easy to handle.
