That was definitely one of the best freestyle performances ever. You have to look at performances, not anything else from the freestyler. Battles don't count either. When I compare this performance with modern day great performances, it still lives up to the standard. This performance is absolutely flawless with perfect execution. Not only are there no drops, but there aren't any signs of a mistake of any kind. Also, he shows a great variety of tricks that keep it interesting. He isn't just doing the same trick over and over again. The difficulty for this performance is still very high. There are either very few or no one that could currently pull off this same performance with as good of execution.
When you analyze most top performances, they even have some slight mistakes. Mr. Woo's is perfect. If this performance was entered into a modern competition, I think he would minimum place, but he should probably win. I still don't know how JF won this over Mr. Woo. JF dropped, and Woo didn't. Also, I think the overall difficulty of JF's performance was lower.
Modern freestylers have managed to surpass Mr. Woo overall with tricks and combos. I agree with this. I do believe that Mr. Woo performances are still the standard bearer of what is top quality. Very few top freestylers put on performances on this level. Performing is a different type of skill than battles or videos. When you compare this performance to the performances that place in the big routine competitions now, it still compares.
