As someone who bought an Xbox One since PS4s were sold out everywhere and I didn't want to wait to order it online, I would say there is no reason, unless you really want to play Halo. Don't get me wrong, it is a good console and I've enjoyed Destiny on it, but my main problem is just next gen games in general. There really isn't much out there and the AAA titles for the most part have all had lackluster releases. I play my PS3 and my 360 a lot more than my Xbox One because there just aren't any games out that really interest me or make my next gen console purchase "worth it."
