Stock or new steel flywheel Whats better?

69 GTX 440 18 spline tranny. I have the stock flywheel and it could probably be resurfaced but not sure. Is a new "steel" flywheel better than a stock unit. Car will not be raced and engine should make @450-500 pounds of torque. Car will have 15 or 16 inch street tires.

The stock flywheel is cast, a steel billet unit will always be better than the stocker.
