The diesel is going to have a range advantage with the better fuel economy and has larger aftermarket tank options that are not available for gas at this time.
I echo what most others have said. 6.7 vs 7.3 is really a personal decision based upon the various factors that are important to you and your truck; all are relevant to the truck owner and may be totally irrelevant to every other single person on the planet. It doesn't help really answer the question other than to say there is no answer because no one else knows your intentions for your truck. I also weighed the decision extensively. For me, my main factor in choosing diesel was range.
A 50 gallon tank in the bed (tonneau and 5th wheel compatible) and 60 gallon mid ship replacement give me 110 gallons on board. At 12-21 MPG (my estimate of heavy towing to unladen), that's damn near the entire way from Las Vegas to Washington DC (a route I drive round trip 2-3 times a year) with just a single refueling stop, one I intend to make around Missouri for the less expensive fuel I always seem to find there.
By comparison, a 7.3L getting 8-14 MPG with the stock 34 gallons and no real replacement or auxiliary options is at least 6-10 fill ups if not more.
And no, I'm not driving straight through and stop plenty to stretch the legs and what-not, but the option to not have to refuel every 3-4 hours while towing at interstate speeds appeals to me very much.
