Of course the 10" would win every time, and those are the qualities that make a Sub musical. Cone materials and amplification play an important part also, but size definitely matters. ;-)
Telling a loudspeaker designer how drivers function is as logical as telling a bird how to fly.

Loudspeaker designers never consider 'speed', as all drivers react at the same speed. They also do not consider pitch definition. Those are words that laymen sometimes incorrectly apply to some of the concerns that loudspeaker designers do consider but the layman does not know how to describe in engineering terms.
Cone size in and of itself only affects one result, the angle of dispersion. Every other result is determined by the two dozen odd T/S specs and other driver details.
