Turbos vs. Supercharging

Very loaded question.
If early boost is your only concern, a Mag. SC will give earlier 'max' boost than TT's, but fall on it's face at upper RPM's where the turbos would not. BUT, if you wanted to undersize the turbos, you could get full boost right off idle... but they'd run out of steam really fast.
Like I said, it's kind of a misleading question.

Turbos will offer more flexibility in this regard. Throw on a boost controller and you can affect your boost curve with some degree of granularity. Some controllers offer speed based boost adjustments and some offer RPM based boost adjustments.
It sounds like you're worried about too much power down low?

Generally a properly sized turbo kit will spool quicker than a SuperCharger - exception being the MagnaCharger. Note that a turbo car will carry full boost from 3000-3500 RPM's (or lower depending on turbo size) all the way to red line.

turbos are much more efficient but also much more expensive. with properly sized turbos, you actually NEED a little bit of lag because when the torq comes on it does it big time. the maggie and the cent blowers are much more linear and built boost progressively based on RPMs, where the turbos are "load dependent" and can be sized to spool up plenty quick (and work especially well with an automatic due to the torq convertor).
turbos are harder to tune, and also take alot more of an initial investment. depending on what you want to do, the blower can provide a very nice gain, without so much heat management and complexity issues, but if you want really big power, the potential of the turbos is pretty hard to beat. they are just tough to "package" in the vette unfortunately.
how many f1 cars do you see with blowers???

It all depends on the turbos and the design of the system. Our twin
system with TE32 precision turbos, will start to make boost around
2300-2400 and we imagine that it will have full boost around 2900-
3000 rpm. And the 32's are able to make up to 920 max flywheel HP.

Are you saying that the F1C builds boost early and holds that boost level to redline, or does it build boost early and keep building it until redline?

I can't really tell what you're wanting or wanting to avoid but here's my setup...
I run what's in my sig and having 440 rear wheel torque at 2000 rpms is a blast to....well try to drive I guess you'd call it...I'm moving to drag radials for everyday driving and it should be a beautiful thing.
Here's a copy of the dyno chart...

You can see how the Mag hits hard down low and hp builds nicelt until about 6500rpm and torque starts dropping at 5000.
With the overspun pulley and alcohol injection kit I'll add in the spring I think I have finally reached the ultimate limit of the non-intercooled Mag.
Good Luck
