To make a power supply more efficient, you have to make it better. Lower-quality parts means more heat, more power usage, and more jitter. It's almost impossible to make a bad PSU that is 80+ gold certified, and, to do so, you have to be doing so intentionally.
So, yeah, efficiency translates into quality with PSUs. But, once you get into the higher-efficiency PSUs, you really need to start looking at every other statistic to know if it is a good PSU. Which is what the previously-mentioned review sites are for.
And, there's a very low chance that people aren't just jumping the gun based on old Rosewill PSU performance, and saying things that aren't even true about the Capstones.
EDIT: Also, don't read the ratings on the provided charts. They're normally either in optimal conditions, an incredible sample, peaks, or any mixture of such. ALWAYS LOOK FOR A REVIEW OF THE PSU THAT YOU ARE LOOKING AT, WHICH IS DONE BY SOMEONE LIKE JONNYGURU.
