The one that is on your boat.
In all seriousness, how can one really tell? What makes a good surf wave is the combination of hull, ballast, and the surf system. Unless you put the same surf system on the same hull and test in the same conditions, who can really say which "surf system" is the best? Even then, it is going to be all up to preference.
All I can say is the NSS on my G23 works well.
