I think for daily use, any wheel is okay.
For autocross - same, but weaker wheels might fatigue after many thousands of laps.
Of course this assumes no defects in the wheels (like viods inside a poorly cast wheel).
Where the quality of the wheel is important is two areas; 1) weight - Forged can generally be made lighter.
2) Severe incident strength - Forged wheels rarely break in an accident, and will hold up to repeated impacts
(like driving over the 'gators on a racetrack) much better than the more brittle cast wheels.
I use only forged wheels on my track cars.
Bottom line - unless the wheel is defective (casting voids), you can probably get away with anything for autocross.
All this is my opinion, of course.
