Microsoft has the better lineup IMO. They're bringing in a ton of new IP that look really cool; Quantum Break, Sunset Overdrive, and Project Spark all look like must-haves to me. On top of that, they've still got franchises I love, they've still got Halo, which is my favorite first-party franchise, better than anything Sony's got (even Uncharted, which is a FANTASTIC series, I've got nothing but respect for Naughty Dog and their work).
Right now I'm not seeing much on Sony's side to sway me away from Xbox. Killzone and Infamous are fine franchises, but they didn't sway me to the PS3, so they aren't likely to do it with the PS4. Knack hasn't impressed me in the least, other than it's neat art design. The Order might be the only one so far that seems kinda cool. And the indie games they showed off didn't interest me, with the HUGE exception of Transistor, which might still come to the Xbox One.
