I'm not sure on the LT1 breakdown, but I've worked on A4 LT1 cars that came from the factory with 3.23s and a steel shaft, so I know the breakdown is not the same as the LS1s.

Steel is stronger though. But it's not much of an issue unless your making some big power.
Main reason I like the steel shaft is because it's "tink" free. Both LS1s I've owned with the aluminum DS have had this TINK noise when going into gear. The steel shaft doesn't do that.

Mechanical/Automotive Enginer ON:
While the steel used in driveshafts is somewhat "stronger" (tensile) than aluminum, most to all aluminum driveshafts will have considerably thicker walls to compensate for the lack of strength...therefor the "strength" issue is negliable. Another point to consider when considering an aluminum shaft is fatigue life (which is not unlimited with Al) and drivetrain harmonics.
/Engineer OFF.
They're both the same when comparing two correctly designed driveshafts.
