There is no correct answer. Just understand that the power from a SC is a linear delivery - ie. power gain is felt all the way across the power band as though you just added another cylinder or two. Turbo has spool, lag and then massive boost. So.. different properties to how and when power is delivered. Turbo will make your car feel like turbo. SC will make your 4 cyl seem like 6. Understand this is like a religious debate. It's not just an easy answer question.
