Im fortunate enough to have all 3, got ps4 at launch and that was a quiet time, could have held off for a year tbh
Last game i needed the ps4 for was bloodborne, since then only really used it for a bit of destiny but stopped that now.
Picked up an xb1 gears deal a few weeks back and other than the terrible u.i i am really enjoying the console. Used to be against the idea of getting one but halo mcc and 5 were must gets imo and now im set for months. It does a few things better than ps4 imo, feels quicker at the front end. Boots up so quick and can just resume where i left off. Though game installs take the wee wee a bit!!
And then theres the wii u, been in a drawer most the year. Did pick up splatoon on a whim, played it twice and returned the wii u to its drawer. Its a great system but feel its more family orientated etc. Tried to sell it a few times but now just cant be bothered lol
