I don’t have direct experience with either of these boats, but there is a fair amount to info on the S211 wave/wave setup on this site. They can throw out a really impressive wave with a little tweaking, extra ballast. Supremes are made in the Central Valley of CA. That’s probably why they are not very popular in NY, but they are a legit boat brand made on the same factory line as Centurions (until the new Supreme plant in GA opens).
If surfing is your top priority, I would suggest a ZS212? The ZS is the new flagship line of Supreme. I own the larger version, the ZS232, and I would put the ZS surf wave up against any other boat in the market segment.
