SuperCruise and FSD currently don't even work on any of the same roads. FSD is for non-freeway roads, and SuperCruise only works on (some) freeways. Autopilot is Tesla's system that works on freeways. (Tesla does plan to merge Autopilot and FSD eventually, and SuperCruise will expand to some non-freeway roads, but neither has happened yet).
SuperCruise is only rated higher than Autopilot when people use rating systems that dock Autopilot for having fewer driver monitoring features, i.e. nanny features that scold you for not paying enough attention. I haven't seen any evidence that the actual driving part of SuperCruise or any other competitor is better than Autopilot.
