As far as style goes, there are more or less two parts:
technical style: control, trickbook, smoothness
this is very easy to identify and very hard to argue
uniqueness: the quirks that make one's style unique and fun to watch.
very subjective to the person. this will forever be disputed.
For instance, I like brown's style because its tech and very smooth, but i am not as big on goeppers because tech wise he can be a little rough (landings), and is a little too stiff for me.
bringing uniqueness into the equation, I love delorme, but i am not at all a fan of hornbeck. here, its to each his own.
People can debate style, but recently it has gotten a bit ridiculous on here. respect that other people like different styles  than you and live with it.
