Google beat 18.104.22.168. It seems like when I tried Google's DNS when it was first made available, it was inferior to 22.214.171.124 but that appears to no longer be the case.
But OpenDNS (which I threw in for the hell of it) beat them both. They do show ads for non-existent hosts, which works my nerves. But maybe since they're for profit, they're able to be quicker.
(Not that this was very scientific.)
