Technical stuff aside, the best reason to buy a Buell is the Buell community. There's nothing like it out there for any other brand I've found. Buell has a great relationship with its customers - right down to posting on our boards - and Buell people are some of the best people I've ever met.
We had a gathering we called Buelltoberfest earlier this month. Dozens of Buell riders from all over the place converged on the North GA mountains. One rider wrecked, and he was immediately surrounded with friends who took care of everything for him. One group escorted him to the hospital while another group recovered his bike. A guy he hardly knew from NC drove him and his bike all the way down to Colombus, GA and wouldn't even accept gas money, just because he rode a Buell.
The rider's response to all of this really sums up why I'll always have a Buell in my garage:
