Turbo all the way. SCs are way too linear (FOR ME). I guess some people like that, I understand that's one of the Ms characteristics but it would be nice if it had just a little more or a lot more under the curve....hence, my good friend the Turbo or Turbos (2) wink wink
Keep in mind the #s are not relative, just look at the GRAPHS.
Like Spiderman's grandpa said "WITH GREAT POWER COMES GREAT RESPONSABILTY" or something like that... anyways just a thought.
BTW I love the fact that you can turn down the BOOST on demand (.5 sec) and with a SC....well lets just say it takes a while. It all depends on taste.
