Has anyone had experience with the two different types of superchargers on similar make/model of vehicle?

I've driven low 10-second/high 9-second PD blown, centrifugal, and turbo cars. I prefer the boost curve of a centrifugal because at lower rpms, they drive like an N/A car, but when you wind them out, they hit hard.
For example, my old '92 notch ran 10.17 @ 132 with a ProCharger P1SC running 17psi. Under 3000 rpms around town, the car drove like a 13 second car. But at the track, I launch at 6000rpms (roughly 16psi), I shifted at 7000rpms (17psi) and when I shifted, it only dropped down to 15psi at 5500rpms. IOW, people brag around the low RPM torque of turbos and pd blowers, but when you're actually racing, you're never really at 2500rpms. So centrifugals have this dr jekyll / mr hyde persona that I like. Tame around town at part throttle, but beastly when you twist on them.
On the other hand, I recently drove UPR's 2010 GT with about 20psi from a Roush TVS. The car runs 9.90 @ 133, so really close to what my car ran. Anyway, driving around town, if you wanted to speed up a little to get over into the next lane just driving along in traffic, you dip into the throttle about 35-50% not really thinking about it and the car tries to rip your head off and crap down your neck. I mean, it's VIOLENT. I accidentally laid about a 100foot burnout IN FRONT OF A COP. You just don't really think about it. PD blowers make mountains of torque all the way down there at the low rpms you normally cruise around in. It's mentally exhausting to drive like that. (to me) It's a lot like driving a Mustang GT in the snow. You're very careful because you know that if you look at the gas pedal wrong, that car will swap ends on you. That's what PD blown cars are like, but in the dry. My dad's 09 GT500 is the same way. Just a disproportionate amount of low end torque.
Maybe I'll have to forfeit my man-card for saying all of this, but I just like the power curve of a centrifugal blower better.
man card revoked...
Man car restored?
