I hold CT superchargers in the highest regards. Just taking on the challenge of creating anything to please some of us incredibly finicky (spell check?) owners is close to suicide. They have done an incredible job and will be sorely missed. About turbos, I drive an FD3S, mostly stock, but fast enough with the sequentials and I personally think it "feels" faster than some of the NA NSX's I've been in. You are right, when turbo cars that have been tuned properly kick in, and heaven forbid if you have twin-it really is an incredible rush. And the power feels endless. Yes many folks go with huge single turbos, but I love the second kick in the behind!
Along with the overly abundant Skylines and EVO's or less popular Subarus if you want to count them, we have a lot of excellent from the factory turbo alternatives here in Japan too. Their is no real way to compete with the power Turbo/SC can produce on a dollar for dollar basis. Here in Japan, the maintenance issue is quite a concern but as you said, the market must suit the customers needs and CT has more than done their part in my opinion.
And on a side note, many folks with the Skyline, GTR's that is, get it for the handling and AWD safety net, not straightline power. Although it is quite capable
