PS4 or Xbox One?

So i don't want to get into a fanboy war but I own both a PS4 and Xbox One - is PS4 still looking like the best choice for Fallout 4 out of the two or are the they pretty comparable?

TBH my PS4 is getting rather full so was thinking about getting this for the Xbox One instead of deleting games in order to make room #FirstWorldProblem i know!
