I don't know, did you like the PS4? If you did, you might as well get another as the Xbox One has a similar library with a few different exclusives(You could look into the exclusives and see if they look more appealing to you), yet slightly less the third party selection that the PS4 has(strangely, it seems to even miss out on some that make it to PC). If you have any interest in fighting games, too, almost all of them are available on the PS4, while not so many have made it to the Xbox One.
I have a PS4, largely, for it's Japanese developed exclusives(including japanese exclusive imports... PS3, PS4, and Xbox One aren't region locked). Being able to screen capture just about anything, and save gameplay footage, is something I've found to be a bonus as well... more for reference though(like going back and checking something I forgot to pay notice instead of going back to check it in game, or being able to pause and look up the meaning within scrolling japanese text). My only negative feeling, is that the stock hard drive is too small for the pushed trend of buying games digitally, and I have a 1TB(limited run console) model(860GB because it needs a fair bit of space to run it's interface I guess), so I can only imagine the annoyance of having to manage 360GB free space of a 500GB model when many games are easily 50GB downloads anymore.
If I lost all of my stuff, and had to choose again, I'd likely still choose the PS4(don't have a gaming PC), but if I could choose a second I'd probably look into getting a wii u or wait for Nintendo's new home console.
