I think the biggest issue with the MarkII were the 30p to 24p conversion artifacts. That's how I could spot the 5d2 footage even with the caption covered. Otherwise, it gets pretty tricky to tell them apart without playing the footage frame by frame.
Having played casually with a GH1 and a 5d2 side by side for an afternoon, it seemed that the ISO ratings on the GH1 were underrated compared to the MarkII. Meaning that at the same f-stop, to get a similar exposure, the MarkII had to have a higher ISO setting.
And to do a "fair" comparison, you need to put a lens twice as wide on the GH1 than on the 5D2, to get the same FOV from both cameras. Then, if you want to match the shots completely, you need to open up the lens on the GH1 a couple stops to get the same DOF on the wider lens (or close the MarkII a couple stops...).
By then, the ISO advantage of the MarkII became not that obvious.
