Unfortunately I have never had the time nor the capabilities to do such a test, but I have shot a fair share of Corbon 135 grain and was very satisfied.
So without a similar head to head comparison, take my words with a grain of salt if you wish.
First off, a few things discredit this individual in my mind (I don't know who he is, so sorry if I offend anyone).
He actually has a category for "Packaging/Appeal"??? What is this, a fashion show??? Also, to me muzzle flash and noise are not THAT important to the function of a defense load.
Also in his ranking of velocity (which is important to me) he ranks Corbon dead last, although it had the highest average velocity from his testing. Doesn't make sense to me. I'm not a stats expert so maybe I'm missing something with standard deviation, etc...
I never had any function problems with Corbon through a G22 or USP40C, but again, YMMV.
So discounting the silly (in my mind) tests like 'packaging, noise and muzzle flash,' it appear as if Corbon did decent in his test, despite his rankings.
I would like to see a credible magazine or gun guru do such a test focusing primarily on velocity, accuracy and penetration among others.
So unless you buy your ammo based on the packaging, I'd give little credibility to this guy's 'test'...
