cp won't transfer file deletions.  Also, what do they call "newer?"  If it's just checking timestamp, then rsync is definitely more advanced.

If you're going across a reasonably fast link (1Gb, or perhaps, even 100Mb) then compression will slow you down.  Should get rid of -z
Should probably add --delete
