It easy to look at the stats but if you go a bit deeper there are some more interesting contenders.
Looking at Pure Skill Antoine Albeau is a great all round skilled waterman. His wave sailing and jumping (and even freestyle - like spocks ) is pretty damn good. At a shoot in Maui he was one of the few guy that had a really good percentage on his jumps - I had him land a big back loop right next to me (I was shooting from the water) and there was no doubt he was going to make the landing and keep me safe. All with a big grin on his face.
For my money Pete Volwater is right up there. He could win races and I saw him bang out to wave 360s in a row on the same wave at Hookipa back around 2006.
And he had double forwards on lock way back in 2000. In 06 Pete was the best all rounder on the planet for sure.
Tati Frans -a sublimely skilled all rounder who can freestyle (his sky high Shakas were the bomb back in the day) and throw double forwards (saw him do it at Hookipa on a proto starboard) and be a serious contender in races too.
I really like the guys that are a bit more all round.
Locally in OZ we had Simon peters back in the day who still is a ripping wave sailor in huge wave and was crazy fast on race gear - nearly untouchably so back in the day.
Byron marsh was amazing - same with Scott mckercher too who racked up PPWA/ PBA winds in racing along with World titles in wave sailing.
With respect, there's a lot more to the sport than waves and PBA style racing. When I checked a while ago, for example, there seemed to be far more pros racing the Olympic class than PBA, with far more pro coaches, and many more nations. And when people compared the standard of the two types, the only evidence ever shown to indicate that the PBA sailors were better was basically fans saying "but they are in more ads".
I'm not saying that the PBA guys are not as good, but Robby could hold his head high in both the PBA and Olympic styles, and at a time when the sport was much bigger and there was much more money to entice people into becoming pros.
