Edmunds recently rated the Tundra higher than the Silverado. MT couyld cover the tundra in the TOTY article because of timing issues. But edmunds said the Tundra was better by the slimmest of margins, and seeing as the silverado does not have its 6 speed available yet, they might just be evenly matched.
