Is Dirac Live worth paying extra for over Audyssey or YPAO?

Specialist subreddit consensus is that Dirac Live generally produces tighter bass and more natural midrange than the built-in room correction on most Denon, Yamaha, or Sony receivers, but the gap narrows once you tune Audyssey manually. The Onkyo TX-NR7100 is widely cited as the most affordable AVR that ships with Dirac Live out of the box.
