I am still enjoying Audyssey Flat + Dynamic EQ very much.
If I can be converted, anybody can.
I've been trying to rationalize why I did not like Audyssey before. And I think it's because I kept on turning off Dynamic EQ for some ridiculous ignorant reasons. When Dynamic EQ is turn off, I see no benefit to Audyssey or Audyssey Flat. But that Dynamic EQ is something else, in combination w/ Audyssey Flat.
I sound like a darn hypocrite. After expressing all this time about how I did not enjoy Audyssey and how I hate EQ. What a hypocrite.
Basically, my impression is that the midrange and treble is the same as Bypass. But the bass is just a lot more amazing. And it's not just the bass-heavy music. Even the bass-light music seem to benefit in the bass. It sounds more well-balanced. I also watched a movie w/ Flat + DynEQ. Also liked it.
So I am now a new-born Audyssey Flat + Dynamic EQ believer.
I have never used the Yamaha or Pioneer Room Correction EQ at home, so I cannot say. I have used the Harman Kardon RC, and it truly sucked. Now that I am 100% sure of.

It's probably because HK doesn't have a Dynamic EQ.
Or maybe certain types of music sound good w/ Audyssey and some music do not sound good. I don't know. I have to play around more w/ more variety of music. I am now listening to Yo-Yo Ma/ Ennio Morricone.
