Area 2.0, Ares 51, I don't care where the firmware comes from, when it comes I just update and never look back. I don't have the Golden Ears of the Gods so it all sounds the same to me. I might get some new goodies like amps or FX though, or some new parameters to toy with. Other then that I've rarely if ever noticed a difference. Which always made me boggle my mind to read some of you giggling like preteen schoolgirls like how everything sounds so different now and how an amp model sounds so radically different it had them playing for hours. There was a youtube vid that did the same riff and lead over every firmware version from 1.0 to Quantum 7.0. I'll include it below. So you can hear the differences in time. Just for the lulz I checked out 1.0 to Q.7.0 to hear the difference. You'd think 25 firmware versions further there would be a massive difference. The only thing my not so Golden Ears of the Gods could discern was a little (tiny) more low end in Q.7.0.
