They serve different purposes, and I actually use both for different reasons. Encfs is seamless, it's encryption that doesn't impede normal operations. You can just mount it and you're off to the races. Duplicity on the other hand is a backup solution. I use it to back up my mail server to S3. It's super handy for that, but it really couldn't be used with plex seamlessly like encfs could be.
