I personally like a billet steel flywheel for my type of use, but aluminum can be awesome in the right application such as autocross, road coarse, and time attack, but not so much for drift, drag, and street.
Lighter so they can achieve faster RPM in short time.
Lack of inertia so the RPM's drop faster. Even when quick shifting
Also lack of inertia allows for engine hesitation and fading on street driving.
I have driven both from 250-600hp ranges and on the street I only go steel, it's a better feel for me. But I love how you can turn out the RPM fast with an aluminum wheel and free up horsepower by rotational mass. However I prefer aluminum drives shafts which have a similar effect.
