If you havn't already guessed, its a matter of opinion.
If you don't tend to wind the engine up frequently when you drive, you will be happier with the 3.0 cams and their low end torque. If you like to work the engine and feel it perform, especially in the upper rev ranges, you will be much happier with the SVT cams. The SVT cams will make more power, but you may need to work a bit more to get it.
