rsync doesn't use timestamps. It looks at the entire file contents for both

I have used rsync extensively for years, and sometimes in rather
exotic ways. It does have a mode where timestamps are used.
I find your conclusions to be baseless. Usually when rsync is blamed
to be slow, it is because it is used over SSH, which is slow.
