Hey mate
I think thats a personal preference, as to which style is better to watch. I myself like both. I think there are many people out there who would both agree and disagree with you.
I think the days of seeing top level riders doing old-school big air tricks in competition is over as they have pretty much pushed this style to the limits. Remember many of todays top level riders, (Hadlow, Lenten and many more who would be considered young by most), were top 10 competition riders back in 2003/2004, (even though they were only 13 years old) and had some of the best board-off, big-air dangle pass combinations going. They haven't ignored the old-school they've already done it.
I know where your coming from though, seeing old footage of Robby Naish jump 20 metres in the air, spin round several times with one foot out the board still looks fooking awesome!!! If you did this on your average beach you would be grabbing more attention than some one popping a perfect Raley 2 Blind, unless the beach was packed with pro-kiteboarders and wakeboarding fans

One person who I believe would agree with you is actually Ruben Lenten. You watch some recent interviews with him and although he will hit sliders, rails and is pretty good at wakestyle, he finds it pretty boring. His thing is going huge, looping his kite like a maniac in the strongest winds possible.
I think one of the best things about kiteboarding is the freedom we have to go out and ride any style we want; Speed, Surf, wakestyle, freestyle old and new.
