I'd think that in "real world" situations most any torquey bike of similar displacement will feel quicker than either a 600 or 1000cc supersport. Which is more or less why they retune the engines for naked street versions (as with the s1000r).
Factor in traffic, and a bike tuned for the street will "walk away" from the other two at stoplights and filtering through ~35mph traffic, simply because it can squirt into openings without touching the clutch. Maybe the 1000cc supersport will have a slight advantage on the occasional onramp, but give me a bike with a wide power band any day.
