FWIK, antiword is the best tradeoff between speed and conversion quality. The best converter I know of, even for batch use, is actually OpenOffice with its "uno" interface, but it isn't that easy to handle from perl since it uses some kind of Java jndi in order to exchange word files and converted text with any implementation of a conversion controller. Also, it tends to consume a lot of memory since current versions keep "growing" core size for each document you convert (even when you close them...). Antiword seems more resource conscious in this...
