AFAIK ksh doesn't have anything like modules or CPAN. You could start there. Nor does ksh have anything like perlmonks. Nor are there proverbial butt-loads of books on ksh. ksh's regular expression features aren't anywhere near as rich as Perl's (but whose is?) Also, last time I checked (it's been years) ksh was *much* slower than Perl. But don't hold too much stock in that notion as implementations do vary. If you're going to pull the speed card, benchmark the two on the systems you are using. As far as raw language features goes, you'll probably get bogged into a Turing equivalence argument fairly quickly. Especially since David Korn himself has said things like "ksh has replaced perl for most of our needs" (or words to that effect). One thing you might want to do (in the spirit of holding your enemies closer) is look at the ksh advocacy and see where it falls short.
