Well I do. I've driven a miata with a medium sized turbo (GT3271) and a big turbo (EFR 7670). And now a miata with a big SC (1.6L pulley'd 2:1) at 20 PSI.
In order of power production, based on seat of the pants/no dyno:
1st: EFR (17 PSI) (landslide victory, lot of power)
2nd: GT3271 (28 PSI) (maybe 350whp, midrange torque was nuts)
3rd: Supercharger (20 PSI) (maybe 350whp, no midrange torque like a turbo though)
That said, from 0-30mph, SC car is wayyy faster. 0-60, SC car is a bit faster. 0-80, GT3271 would probably pass the SC car around 80-90mph mark. After 100 the EFR would fly by both spinning the rear tires in 4th.
SC's are different, it really just drives like a big NA motor. Probably like having a stock LS1 if I reved to 8K to make 400hp, that's what a hot SC motor drives like. It's fun, and it can be powerful.
But turbo motors are easier and cheaper to setup, and that's a big benefit for the turbo. I've done DIY turbo setups and now a DIY SC setup. DIY SC is probably 5x more work! But for me to compare a ~350whp turbo miata to ~350whp SC miata, I'd take the SC no doubt, it's wayyy more fun/responsive, and anyone that things response is a joke, they've never driven a nasty SC'd engine. In 1st gear when you smash the pedal to the floor, the front suspension is fully unloaded before your foot hits the firewall. Turbo motor is at about 106kPa in comparison.
