Most of the State frames I have come across have not had great alignment. The 4130 being made of steel lets you safely bend the frame into proper alignment, unless the alignment issue is one dropout sitting higher than the other. The 4130 also gets you more tire clearance, plus rack and fender mounts.

The main upgrade on the Black Label is a full carbon fork. Carbon shaves weight, dampens vibrations resulting in a bit smoother ride, but is less impact resistant, and is less recyclable than a steel fork. It is essential to use a torque wrench on the stem bolts when dealing with a carbon steerer tube. If you crack the steerer tube, you need a new fork.

Plenty of people use track bikes with aggressive geometry as their everyday bike. I'd rather prioritize tire clearance and fenders.
