This would be a very bad way to make even cheap decisions about components. The three most important determinants of sound are speakers, room software. Note the one in the middle. Now, think about the "listening room" you're doing this highly scientific comparing in. Anything like your room at home? Ixnay. For one thing, the ratio of direct to reflected sound is, well, zero.
The rooms these systems were blasting out of could be having an effect (and a different one in each case). Some systems may have been playing too loud for your friend's taste. So I wouldn't put too much stock in it.
On the other hand, if I were showing off my equipment, I'd make damn sure it sounded good as people were approaching.
