For most people, butt fore-aft relative to the bottom bracket informs and impacts how aggressive a fit is.
Not bar drop?
As for "quick" handling, wheelbase, weight distribution and trail are probably seem to me as having the largest impact. The bikes I illustrated have wheelbases from 96cm to 108cm with more or less the same trail. The front axles align on the 1959 and 2009 with the extra length of the 1959 coming in the rear triangle. The rear axles align on the 1933 and 1959 with the extra length of the 1933 coming from the front end. The short wheelbase is king when it comes to quickness. As to weight distribution, I can't notice the impact as much.
