Well if we’re strictly talking about the ability to hide what you’re downloading from your ISP then the end result is the same.
Except debrid services also gives you premium access to dozens of file hosting sites as well (megaup, 1fichier etc.) - in the case of file hosters the download is streamed to you immediately so there’s no waiting for RD to download first.
Seedboxes will also impose storage limits. In the case of real-debrid you’re limited to 2TB per torrent, or 72 hour download time.
All good, just trying to get the right info out there for anyone wondering the same.
