I think making a comparison based on features is one thing, because it allows someone who needs a quad-chorus the ability to make the right choice.
When a comparison is made on something as arbitrary as how many operations per second a processing unit can make vs. another it shows an attempt at undermining the value of an item without equal comparisons.
That is to say, I could build a multi effects device with dual quad Xeon cpu's and process enough instructions per second to land a space shuttle... but without quality algorithms, interfaces and end user experience, it's nothing but a pile of bolts and sheet metal.
I guess the point is, arguments of arbitrary foundation suggest desperation or lack of understanding.
