Turbo. Turbo all day. Superchargers are insanely expensive, and you won't net a considerable power gain from them (even running a Jackson). They're different, yes, but who gives a s*** what everyone else is doing? Do your car for you, and no one else.
You have a lot more flexibility for boost with a turbo. As others have said, don't run a huge ass turbo, and you'll be fine. If you build your bottom end and do a little bit of valve train work, you could run a GT30 and make 400whp on 91-93 octane. Since it's not your daily, it's very feasible.
