They are a LOT less expensive than Chris Kings. You are right about the steel vs alloy freehubs with regard to durability. Over time, The cassette tends to dig into the alloy spline under hard use. But I've stuck to alloy for weight. And iirc the steel ones were more expensive, but I may have made that up as a post-hoc rationalisation of my choice.
