I just don't get this statement. If it is so much better there should be objective evidence. There are also those, like me, that have used it and not noticed any difference at all.
I wish someone would do a blind A/B or maybe even A/B/C/D comparison to see the difference in subjective quality based on a group independent opinions. Not to be a complete ass here but placebo effect is very real and very powerful. I deal with it in my real job every single day.
