I will say that I have made beer that I think is superior than some stuff I've bought. But duplicating a clone is different. Even if you have the correct ingredients in the right proportions, the brewing process can change it dramatically. Different mash temps, fermenting temps, water differences...the minute details are almost endless. I wouldn't measure success by comparing a clone to the original. I measure it by ending up with a beer that is a great example of it's style, but most importantly, tastes really good.
