It's just Greg Miller's oppinion, nothing more, the mistake he made was to state it as a generaly acknowlaged fact.
They are both GOTY materials, but Mass Effect has more depth, while Uncharted better pacing and action, also is a lot more polished. If I were to judge these games now, 3 days after finishing Mass Effect, I'd probably go with it, as it's more recent experience. But if I were to rate these games, UC will get full score, and mass effect couple of points lower.
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
