nope
PS4 has exclusive content. Exclusive Guns and Missions.
Also it's smoother on the PS4 with it being 30fps constant but frame rate dips on the XB1 constantly.
Again everybody knows this is the case with 99% of games on both consoles. PS4 versions are superior. I don't want to turn this into a console war, everyone knows the PS4 handles games better.
He is likely going to lose money on selling and rebuying. Which could go towards a psn sub. IMO it is stupid to have 2 consoles and only 1 online sub. Unless you plan on buying all multplayer games on one console. If you were going to do that then surely you would buy them all on the superior console.
This will be my last post in this thread as I know what it's about to descend into.
OP keep the ps4 version and buy psn plus would be my advice.
