Super rocs are Racho rocs. They are made of a champ/pro blend, which tends to make them more stable than their dx/kc counterparts.
Ontartios are indeed less stable. They fly straight out of the box, and power players can turn them over out of the box. They beat into turnover discs.
San Marinos are between Ontatios and Rachos, but beat into the straightest flyers quicker, and stay there as long as a Racho.
Rachos are probably the most versatile of the 3 because of their ability to turn twice during their flight (turnover, fade back). I've only thrown broken in San Marinos, and they just fly straight.
edit: Wow, I didn't realize that Ontarios were more stable than San Marinos. In my limited experience with Sannys, I didn't feel that was the case.
