Compared to test director, bugzilla is cross-platform. HP Test Director [now part of Quality Center] needs a ActiveX control on client to work. This may not be problem for you but is for many people.
Test Director also has a very bad reputation for security problems. Almost all security for it is done on the untrusted ActiveX client and not on server! Do not use test director if users are not 100% trusted.
