A turbo is ALWAYS better... period. Anyone who says otherwise is just playing favorites. More power, zero parasitic loss.

From a pure performance/competition standpoint turbos are king and don't let anybody tell you different. However if money is a factor at all a super is a much better option given that a "properly" set up turbo system is going to be far more expensive, but worth it. It also may not be so ideal for a street car to go turbo rather than super for fun purposes. Only place I know with enough room to stretch a turbo's legs and feel some boost is the highway. But i've never driven a turbo'd stang.
