Adding the interactive function for syncing seems to be a good thing.
But what troubles me the most is the namespace wasting.
Instead of creating n number of compare-windows-sync-* functions
it's better to create one interactive function
(e.g. compare-windows-sync-windows) which when called with argument C-u
will ask the user for a function name (e.g. forward-word,
forward-sentence) or a regexp (anyhow, one of your proposed functions
asks for a regexp) and will set the buffer-local compare-windows-sync
variable to this function or regexp.  If the compare-windows-sync-windows
is called without C-u, it could use the previously saved value of
compare-windows-sync.
