I'd say Duffy is quicker than Dunne ever was, and he turns quicker too. Dunne turned like an articulated truck and, while he had a quick burst of acceleration, it looked like more because he was such a big unit. Duffy is a lanky ****er and covers a lot of ground without looking like he's doing much. What he doesn't have is Dunne's positional nous and nose for danger but, then again, neither did Dunne until he was pushing 30.
