It's not attached to a mechanical drive from the engine, it's propelled by the exhaust gases from the engine. That's where the issue of lag and delayed power delivery comes into play. Now, there is a solution to overcome some of the inherent issues that a turbo'd engine has. An electrical motor that is mechanically connected to the turbo and that can change the rpm of the turbine shaft. This is a more technologically advanced solution than attaching a supercharger to the crankshaft pulley. Not to mention that it doesn't steal power from the crankshaft to be driven (taking into consideration that it also can regenerate power from the turbo).
Whether such a engine's power delivery will feel more artificial than a engine with a mechanically driven supercharger and a turbo is hard to tell without having testdriven one...
To some, any turbo engine will feel artificial compared with a NA engine's power delivery.

I agree with all of that even if exhaust driven is not mechanical it has a more analogue nature that is naturally in sync with the engine by being produced by the same combustion engine that is btw driven by gases itself
Maybe none of this matter as long as there is always more pressure than used but if all of the pressure available from the low rev source is used it could matter.
