That sounds like a reasonable explanation.
wget and ftp tools will just cause more traffic for both servers, as
they usually can only append to files which were changed, things usually
requires re-downloading the whole file. So they recommend rsync.
But these files (linux distribution) are not expected to change once
published - if there is a new version then it's a new file anyway, so
the rsync algorithm wouldn't kick in to transfer just the parts that
changed.
I can say I use rsync for all the mirrors on mirror.{hamakor, isoc,
iglu}.org.il.
That by itself doesn't prove rsync's advantage. Can you provide some
traffic numbers showing that it benefits
speed/bytes-transferred/cpu-utilization or somesuch?
Right now I expect rsync is practically used as a smart mirror (in the
sense of copying files and keeping their timestamps) since the file
diff algorithm wouldn't come into play.
