If we're going to talk about big pluses for street cars, turbocharging a street car not only offers better fuel economy than supercharging, but that little delay/lag in power delivery actually provides a small cushion and doesn't beat on drive train components nearly as much as supercharging. Not to mention being able to dial the boost down for your less aggressive trips to the grocery story and only breaking the tires loose when you intend to do so.
Too much credit is given to supercharger throttle response. Sure it's great for burning the tires at a stop light, but not very good for a hard pull on the freeway. Big bottom end and moderate mid/high range isn't as exciting as moderate bottom end and big mid/high range on a street, track or drag car. I don't mind waiting a couple milliseconds for my turbo to spool.

this is just me, but lag is lag. you can stand it, but you never want it. non linear power delivery, while it feels good when it kicks in, is never ideal.
i also disagree that the "cushion" is good. that "cushion" is load. if you're in high gear and you WOT, you're putting tremendous load on the engine. yes you can downshift but that's irrelevant to the point.
moderate mid-high? what are you talking about? are you thinking of the old school V8's that have everything down low? look at this dyno, gains across the board...
and after a flash tune:
so for me personally, unless you are not satisfied with this performance level, and must have more power at the expense of lag, then and only then should you go turbo. ymmv...
