I personally prefer xbox, i play forza alot so that could be a biased, but i think xbox has better exclusives, i also feel like xbox is much more sleek and easy to use, so i feel like xbox is best for your causal gamer, with the way Microsoft is owning more and more companies, it may be smarter to buy and xbox. I also feel like xbox gameplay is much smoother than PlayStations, but the down side of xbox is the amount of of players, PlayStation is like the apple of the console world, not necessarily the best but the most popular.

Personally i would go for an xbox, but just look at exclusives and prices ect.
