Since you don't care about the media aspect just look at exclusive games and figure out which side's games you prefer.
XB1 currently has Dead Rising 3, Titanfall, Ryse (just don't, please, it's crap) and Forza Motorsport 5 out and Quantum Break coming in the near future while you'll also get the expected Halo and Gears of War games.
On PS4, you've got a better lineup of indie games along with Killzone: Shadow Fall (this game is almost as boring as Ryse), Knack, inFAMOUS: Second Son (my favorite new-gen game so far) and the Final Fantasy XIV mmo. Then things like The Last of Us: Remastered coming out this summer, Uncharted 4, The Order: 1886, Gran Turismo 7 are coming along with your annual MLB: The Show.
I also expect more exclusives for each console to get revealed in early June during E3.
Another thing to consider is, which side are your friends playing on? If playing games with your friends is a priority, then that should factor into your decision as well.
Personally, I'm a bigger fan of the exclusives Sony puts out, but then again, I'm a massive Forza fan, so I own both.
And for fucks sake people, stop turning every damn thread in the Arcade into a console war.
