To give an answer to your question, I will go with supercharger.
I will much prefer having both, when the supercharger kick-starts work immediately the engine is on, with time the turbocharger too starts, which gives me an edge over other cars ..
Don't really like It when other cars overtakes me on the road based on better engine..
Nice post sir, thanks for the orientation.
Hmmm.. Yeah nice one there so you prefer the twin charged engines.
