SV - more bang for the buck... More power, more reliable (well, the Ducs have gotten better at this lately but still...) - and cheaper. The riding position of the "S" is more forward and "sporty".
ducati still has a bad reliability rep, if you dont mind that could be a way to stand out, but suzuki is a better bang for the buck (as previously mentioned), depends how much you ride, and how much are you willing to spend on the bike
