Some people called it "Harman curve".
Take a look of the tilt Amir used in his review:
Audyssey Room EQ Review | Audio Science Review (ASR) Forum
If you had used such a target curve, you might have been happier even without using DEQ. Without using DEQ, and without tilting the default flat curve, I can understand why so many people would not use Audyssey, unless they always crank the volume up to near reference level. With DEQ on, most would have been fine with Audyssey, and using DEQ is the right way even for normal people.
