FWIW, I ran two sets of steel wheels. 15x8 and 16x8.
What I did like: the blacked out look, the cheap price of the wheels.
What I didn't like: the tolerance of manufacturing and weight. The later resulted in an overly difficult time getting them balanced and not causing wobbles.
the runout of the steel wheels is much worse, usually two or three times that of an alloy wheel. thats because steelies start out as sheet metal and are welded together, but alloys are machined from a solid piece.
on top of that, the 16x8 steelies were 21 lbs heavier each vs my current 15x8 Procomp alloys. thats 105 lbs total savings, including the spare.
That 21 lbs per wheel really makes a difference in ease of balancing and keeping wobbles away. If you like the black look, go for black alloys.
