I got the system with my new boat and to be honest I can't really tell the difference, as the difference between my old boat and the new one is huge and I can't pinpoint it to one particular item.

I guess unless you are a top sailor you may not notice much difference in performance, however with the system it is much easier to rig and takes a huge amount of tension off the cleat at the mast base. The top sailors in our fleet all have this system on their boats and speak highly of it, so I guess it must be better overall.

In Hong Kong, all of our boats come from Australia, so all the new ones are coming with this system as standard.
