Not enough info to decide.
Sure the PS4 conference had games...but the only interesting ones for me were obvious third party titles that will be available on all systems. We still don't even know the price, release date, or launch titles of either system and people are already comfortable choosing which one they want? Seems weird to me.
I feel like I won't know which one I want until a good 6 months into their lifespan. I want people to have time to dissect the architecture of both machines and find out if one provides significant performance abilities over the other, etc. Also by that time the game catalogues will be a little more fleshed out.
