replace starts to pay for itself when you need to process multiple files
or if you want to swap character strings.  For example,  
replace a b b a -- *htm
will swap the strings a and b around in all the files.

For simplicity, I think replace wins.  For overall power, sed wins.
That's one of the nice things about Linux - we have a wide variety of
tools at our disposal that may be capable of doing the job.
