I don't really think there's any contest to this. PS3 has gone from a laughing stock and potentially dying/dead console to having a major upswing in features, THREE price cuts, tons of exclusive and cross platform content and a total image change. All in about a year.
If anything, the PS3 has improved the most because it started off as one of the most botched and mishandled console launches ever. And is now competing with XBOX360 head on and looks like it'll surpass it.
