Ok, first of it depends on the power potential you want and where you want the power.
Turbo's are more efficient and generate a better HP output since they run off the un-used gases and exhaust pulses expelled from the engine. A S/C will drain the engine of power due to using the crank's rotational mass to turn the turbine.
Yes turbos will HOLD more heat but they do not generate any more heat than an exhaust header. Get the turbine housing coated in ceramic or jet-coated and it will hold the heat to keep it from radiating. This will effect longevity but with a ceramic ball-bearing turbo the heat transfer will be minimized. Also adding an oil cooler for the turbo and one for the engine will help prolong the life of the turbo.
Power in a S/C is instant... it builds boost with the RPMs and thus builds power constantly. Turbo's must reach a specific RPM to build boost and without a mechanical link to the engine it has to rely on the speed and momentum of the expanding gasses within the turbo-manifold.
As far as the more expensive... Yes the TRD is complete right out of the box for $4995 or less, some times. But with a Greddy or home built turbo kit, not only will you spend less (if you know how to shop) but you will generate better gas mileage and greater output (if you know how to tune properly).
Simple fact, it's a personal choice but the numbers and general logic ALWAYS point to a turbo every time. It's an emotional choice that directs to supercharging.
