I'm a Sony boy. I love their IP's and their approach to general game design and letting their studios experiment. But Sony really has dropped the ball on a number of features(mainly hardware related) that Microsoft has just knocked out of the park.
1) The Elite controller. I wish Sony made something like this. Yes there are 3rd party controllers with similar features but they are not made by Sony and do not resemble the Dual Shock 4 which I prefer. I have the Nacon Pro and a Scuf Dual Shock 4 controller and I much prefer the Scuf because it is essentially a Dual Shock 4 with added buttons and longer sticks. Problem is I waited 4 weeks for that controller and paid alot for it. No local warranty either(I'm in Australia). An official Dual Shock 'Pro' controller would do away with all these problems.
2) 4k Blu-Ray playback. MS implemented this in their base Xbox One S console which can often be had cheaper than a base PS4 console. Sony did not even implement this in their premium/4K focused Pro console which is sheer lunacy in my opinion. When I heard the Pro didn't include this feature, I decided against getting one. I would have bought a Sony UHD TV alongside it because my current TV's are only full HD(Sony Bravias).
3) Supersampling enforced via hardware. With the Xbox One X, supersampling is available for every X enhanced game for 1080P tvs so you get a cleaner image with less aliasing. Where with Pro it is essentially upto the discretion of the developer.
4) Xbox One X power. I initially stated that we wouldn't see many true native 4k games on the Scorpio and it would mainly be indies and AA titles but I was wrong. Rise of the Tomb Raider does run at native 4K on X while Wolfenstein runs near 2160P alot of the time. The 6TF VS 4.2TF difference is vast especially with the extra RAM and higher resolution textures. If I want the biggest jump in visuals from the base PS4, I will be getting the X.
5) X is smaller/runs quieter compared to Pro
I do think that when OLED TV's become cheaper in the next year, I will be getting the Xbox One X instead of a Pro. It just promotes 4k gaming and content(blu ray) more.
