I recently made the switch and had the same questions.

The 4S hook on the street all around better. The 4S are very quiet. Comfort doesn't feel any different. I don't drive mine in the rain or cold but what is nice is they don't require any real warmup time before they hook on the street. Car is 710+whp (mustang dyno).

The SC3 were very consistent on the track (raced it on road coarse a couple times). I have no feedback on 4S track performance and will likely choose something else on different wheels if I head back to road coarse track.
