I've nearly always been happy with the shifting quality and durability of steel chainrings, even as some of Shimano's lower-tier, early-90's steel middle rings (having chain-pickup features stamped instead of riveted) gave a rough transmission feel while JRA. Those particular steel rings were an unpleasant addition, but these Campagnolo steel rings look quite decent and probably work smoothly and shift very well.
This is the first I have seen of steel Campagnolo chainrings however.
