One thing about turbos is that at small throttle openings they are very benign. It requires some skinny pedal to make boost. A Maggie would provide the best small throttle response of the three I would guess. My experience is a bit dated but my 10-71 big blocks would tear your head off on ten pounds of boost with just a tap of the throttle. My turbos were not so immediate but once they came on boost a V6 Buick would destroy the big block.
