Totally agree here.
The PS4 accessories are definitely not as high a quality as XBO's.
Like you say Id definitely purchase a 3rd party HDMI for PS4. The Xbox One feels much better. I like both controllers, though the PS4 analog sticks are way to loose. Better than DS3 but still to loose. ( AND THE WRONG POSITION ).
The headset on PS4 is atrocious. Its terrible. Sorry its really bad. You think there a few people out there repeating Kinect vice commands. On PS4 headset you'll sound like a kids broken toy. SORRY MATE WHAT DID YOU SAY!. HELLO!
Also the packaging is a lot nicer on the Xbox One. Feels more premium. The consoles both feel good though. Although I prefer the media centre look of the One rather than the console gamey feel of the PS4.
