Those two units are similar in price from most online retailers, with the 430EX perhaps a bit higher.

Both good units with their pros and cons. This page (http://photonotes.org/cgi-bin/flash-lookup.pl?flash1=sigma500efsuper&flash2=canon430ex&flash3=*)gives you a side-by-side comparison.

Either one will meet the needs of 99% of photographers, 99% of the time.
