Replying to Spinoff: How Do You Judge a Contest Based on Style?

This is a HUGE issue I have with the whole NS movement of "every contest should be based on style". There are a variety of different styles out there, who decides which is "better" or "worse". Max Hill and Phil Casabon for example. Lets say they both do the same trick. Both will no doubt be full of style, but how do you then judge that? Whose is "better"? Style is entirely subjective, so how do you judge it?
