Chinese counting is just as fast once you're used to it. Remember that you only need to count one player under Chinese rules. And the AGA rules are a nice hack to Japanese rules to make them always give the same result as Chinese rules and avoid trolling/unreasonable plays, but it's still more complicated to explain to beginners than Chinese rules.
