Well, there are about 4 times the number of 767s out there. Airbus has only delivered about 200 so far.
One thing the 767 has going for it is an excellent safety reputation. 20 years in operation in large numbers, and only a single crash caused by a design fault (which was found and fixed quickly), and none from pilot error. There have been one and possibly two accidents due to criminal acts, so they don't count. This kind of record is quite rare, and speaks loads for an airline's peace of mind about an aircraft. The A330 has not been in service long enough to have a meaningful comparison.
That said, and speaking as a spotter/photographer, the 767 is one of the most boring-looking planes ever built.
But it works.
The only thing you should feel when shooting a terrorist: Recoil.
