I'm still catching up on PS4 info as I couldn't watch the conference due to time.
From what I gather so far it wins though. £79 cheaper, FFXV (should still be called Vs.XIII but oh well), job done.
That said I don't think there's enough on either console to actually warrant my money on release or the Christmas which will quickly follow release. My 360 will probably stick around for a good while yet.
