What do you think the best power/drivability combo is?

I run a 3.23 sure grip on my single turbo 5.9.
Highway cruising is smooth and with the turbo I have power on demand. It will smoke street tires in 2nd gear at 50mph. It's a great balance between power and drivability. I think the next best combo would be a strong stroker N/A and similar gearing.
