It's actually very hard to tell if Richie is a better skipper than Cozza as he has the advantage of helming a much better side right now. The quality of a captain comes through much more clearly in adversity and Richie's time for dealing with that may well come (presumably when he moves to Saracens in a few years?)
But I should have broadened the point beyond Richie as I don't think there are any stand out skippers at the moment. No Eales, No Fitzy's and no Johnsons.
McCaw may well be the pick at the moment (I don't think Smit is thats for sure!) but I've not seem him really galvanise the ABs under adversity yet. Perhaps I haven't seen the right games.
