One more point in consideration would be to go through the "exclusives" game library of each PS3 and Xbox360. PS3 seems to have more adventure based exclusives like Last of us, Uncharted, Beyond: Two souls. Xbox 360 has one of the best action games ever Halo.
I went for a PS3 because it comes with a bluray drive. For larger sized games, you have to swap discs in Xbox 360 (I heard that for a couple of games)
Xbox controller is ergonomically better than PS3, but after sometime you get used to it.
PS3 comes with a wireless controller by default and with an inbuilt battery....
Move is good but as someone rightly said for Kinect, after the initial excitement wears off, it just gathers dust (like mine is too).
Would not suggest PS4/Xbox One at this moment because its the first version, remember both PS3 and Xbox360 first versions had some issues. Plus if you haven't been gaming on current gen, you have almost 7-8 years of titles to choose from. And still new titles are released.
Cost factor

S3 machine is half the price of PS4. The most expensive game of PS3 is cheaper by Rs. 1000/- of PS4 (I think)
PS: Sorry, after posting I noticed that the OP already bought PS3....
Congratulations!!!
