Although the 360 was my first out of the two, therefore in theory I should have great memories of it, I don't. The PS3 wins for me simply because it has more games that apply to me and has many more exclusive titles that I want to play. Franchises on the Xbox are limited and easily forgettable whereas the PS3, in my three months of owning it, has given me more joy than the several years I've had the 360.
Neither console is the best, but some innovations and specs are greater than each other. In the end they're both good and have contributed a lot to the evolution and devolution of video gaming.
