The attraction of rsnapshot is that it uses hardlinks + rsync so space usage is minimal.
The attraction of backuppc is that it merges identical files on different hosts - so it requires even less disk space. (e.g. I'm backing up 10 Debian etch systems, so I have ten identical copies of /bin/ls - backuppc will notice that and only store one copy on disk :)
Duplicity looks very nice because of the encryption, but once I've seen the space-saving the backuppc achieves it is hard to move away from. (It uses hashes of file contents - so sticking in encryption would break it.)

Right now I'm running backuppc, and rsnapshot on my systems.
