Well, I already have a Bluray player, so it seem to me having a PS4, Xbox One and a Bluray player under the TV seems a bit silly (besides a Roku, Sky+, a CD player and a Xbox 360). But I like my harmony remote, I like to centralise things, and minimise having too many boxes (I already have too many boxes) and remotes. So having decided to get rid of the Bluray player, I now have to use one of the consoles to watch films. I found out the harmony work with the Xbox One by accident. It means I can treat the XB1 as a Bluray player, not having to get a separate remote (the controller) to watch a movie.
I would add that, it is not a problem using a controller, but it is just more convenient when watching a Bluray with the XB1 than the PS4.
I know a lot of the things on the PS4 works fine, the app is fine, the avatar is fine, the OS is fine, but the same things on the XB1 works better. It is simple as that. The friends list is better designed, the Avatar is more fun to design, the Smart Glass has more features (have you seen the latest TV thing? To be able stream TV through it). Although I shouldn't dwell on the TV thing too much, the PS4 will never have that, it wasn't designed with that in mind. But if you have both consoles though, the disparity becomes quite clear. It is not a case is which is a better console, it is more that I like my XB1 more at the moment because it feels I am getting more for my money.
