Some benchmarks give SAS a performance advantage and some SATA. It probably depends a lot on the drive and host configuration. Both SAS and SATA have different ways of going about queued commands, and I'm not sure either is a clear "winner".
Note that they don't yet make platters that can max out a single SAS or SATA bus yet. So it doesn't really much matter. You are always limited by the mechanics of the drive these days. For single-device buses like SATA bus speed won't matter until we get faster mechanics.
