Just keep both consoles, theres bound to be a game coming out next year that you'll want to play and if its on the console you sold then its a pointless exercise as you'll most likely buy the console again anyway.
Ive got both and my XB1 is a dust collector atm, it hasnt been used in months whereas the PS4 is used almost daily.
