Makes sense. I have seen quite a few threads on neogaf with psn having issues while I rarely see any talking about xbox live.

No one should be surprise by this..

Comparing it to PSN doesn't mean it's the best lol

Sounds about right.

No surprise there, it's always been the best gaming network.

Expect to see this in all their ads from now on.

Its been the best since it launched.

And who paid for this study? MS?
And its only between "Xbox Live and PlayStation Network" ?
