Garage works well for its limited feature set, but it doesn't have very active development. Apparently they're working on a management UI.

Seaweedfs is more mature and has many interfaces (S3, webdav, SFTP, REST, fuse mount). It's most appropriate for storing lots of small files.

I prefer the command line interface and data/synchronization model of Garage, though. It's easier to manage, probably because the developers aren't biting off more than they can chew.
