External HDD on XB1 is a big plus compared to PS4 IMO even if you can change your HDD on PS4, I would have preferred external HDD.
The fast UI, screenshots with one button (and since launch), playgo, 15mn of past games always being recorded (that function always worked perfectly for me) and Spotify are really big features on the PS4 though (for me).
