Mostly it is a waste of money because thinner chains are unlikely to last as long while costing more.
It isn't the spacing between the rings, it is the teeth of the ring. The bottom of the teeth is wider and the new 10sp chain didn't seat properly and I believe it caused the skip and the noise. The other possibility is that the teeth were worn too and didn't grip the chain, or both.
