Assume the PS4/XBOX One hold no interest?
If not, then either will be ok in all honesty. I just bought a PS3, after selling my Xbox 360, as wanted to play all the PS3 exclusives that I have missed out on over the years. Apart from preferring the Xbox controller, everything is much of a muchness.
One thing, the PS3 has a Blu-Ray drive, which might be handy if you have not got one already. In relation to non-gaming, they both can run LoveFilm, iPlayer etc, so are quite useful if that's your thing.
As for prices, there doesn't seem to be any massive price drops with the advent of the newer models. I paid £220 for a 500gb PS3, Beyond: Two Souls, The Last Of Us and Fifa 14 from Amazon.
