I own both, and lately I've been wondering why. There are more and more console games getting ported to PC nowadays I might as well sell them both. If I had to choose, I would pick PS4 because Sony has actually put out exclusives I care about. PS3 had so many great exclusives and new IP's that if PS4 can have half as many it will be worth owning. The Microsoft exclusives that I actually care about seem few and far between. I used to play halo 1+2 somewhat competitively and they are still probably my most played games but I just don't like the direction of the new ones, the only other exclusive of theirs I like is Forza but there are plently of other options for racing sims.
