It is important to define what is meant by "rsync". For example, a common rsync operating mode is to simply compare whole-file timestamps and file size in order to determine that a file has changed. However, zfs surely works at the zfs block level so it does more work due to files being comprised of multiple blocks.
Rsync may be executed in a mode (--checksum) by which it compares blocks of data. This mode would be considerably slower.
