After a few years out from console gaming and trying to get along with steamlink and the steam controller I had a similar decision to make.
Even though most of my mates had ps4 it felt like the xbox one s had a slightly lower running cost - things like ea access for £20 for the year give you a decent catalogue of games, offers on the likes of cdkeys, the now painful process of buying from likes of xbox sg and russia - whilst not really giving much up in pixel peeping contests on youtube.
If i continue to enjoy the xbox (and ori and forza have blown me away) then it should be a fairly painless upgrade to the xbox scorpio for me in around 18months time.
Other peoples mileage will definitely vary
