Daniel, I think this is really kind of a loaded question! Its going to be very subjective as far as answers. As you stated, there really are so many variables, and that, being mixed with each persons own personal experience and preferences. Why dont a person just make up their own mind, by shooting a wide variety of each. Sure, it will take time to do in order to get a true and good broad scope, but its really the only way to know what feels best for one's self.
As for myself personally, I like the r/d longbow.
