I agree with you OP. I find the xbone to be a much better experience than the ps4 this gen. The zeitgeist surrounding this gen, especially on NeoGAF is that the ps4 is the superior console. Not saying that's wrong, everyone has their own opinion, but for me I simply don't agree with it. The xbone just feels like a more connected, sophisticated and "next gen" experience.
I owned and enjoyed both consoles, but despite the power difference I started buying 3rd party games on xbone because of the superior overall experience. I agree with all your points, and I'd also add in the "record that" feature and how easy it is to share clips and screenshots. It just makes the OS feel alive and connected.
The Xbox app is also really great, another area ps4 is just inferior in.
Again not a system wars post, just my experience this gen.
