Xbox's media capabilities are superior to PS4. So you are wrong.
Specs I think is arguable, the specs are so similar with a few differences, which each have their advantages and disadvantages in specific situations.
Best exclusives is an opinion, which I will state I personally own and play more X1 exclusives than I own PS4 exclusives.
Stability of Apps is arguable, given that all media apps on PS4 have crashed for me (fairly consistently), but X1 performs perfectly with media apps.
Best versions of multi-plats is also arguable, majority yes run better on PS4, but I'm certain there were a few that ran better on X1.
Best 1st party studios... uh... yeah... that's probably true.
EDIT: I actually went and looked at my collection, I actually do own more PS4 exclusives, because I think Hearts of Stone physical box was PS4 only, but all of my PS4 exclusives are sealed because I have no interest in playing them as they are all for my wife... minus hearts of stone, because I don't own Witcher 3.
LOL...I was making a funny. But since you replied....
1 Xbox One does have more multimedia features. That is precisely why Xbox lost before it even began: The focus away from gaming.
2 Specs aren't arguable. PS4 demonstrates on a consistent basis it can perform better than the 'bone with higher framerates and higher resolutions. Sure, there may be the odd game that runs better on Xbox, but the overwhelming majority are superior on PS4.
3 Check Metacritic and Game Rankings and you will see PS4 has a higher average than Xbox One for exclusives. Sony has also turned the tables in most cases on Microsoft and beat them at their own game of buying timed exclusives and timed exclusive content.
4 Experiences like mileage will vary, but listening to members here and on other forums, it's clear that Xbox has issues with consistently streaming content and performing downloads. It is painfully slow compared to PS4 in most cases.
5 See #2. With the odd exception, PS4 trumps Xbox One every time.
6 You admit Sony has the better 1st party studios. You further admit to personally owning more PS4 exclusives.
See, Sony wins.
1. Yup
2. Yup, but that's my point, it kind of depends on how you develop your game, as such, if devs see PS4 as the better seller they will develop specifically to make it for PS4. Sometimes devs look at it the other way.
3. Eh, I don't judge games based on their critic or user ratings, but yeah games like Halo 5 don't help.
4. Actually yeah, installing games and updating games is so painful on X1 that multiplat I go PS4 just for that.
5. Also, See 2.
6. Yup, but that's because Microsoft ditched all their 1st party studios, saw that was stupid, tried to fix it, failed rather miserably. Halo team doesn't know what they are doing, not too impressed with the new Gears folks work, Fable has gone to shit... but Forza is still pretty great. Objectively speaking, I have no issue admitting Sony's first party teams are worlds above MS's first party teams, but I personally like the MS exclusives over PS. I think we've had this conversation before, I won't argue and say shit like Bloodbourne sucks, I don't know if it does, I haven't played it. But I also don't care to play it. Whereas on the other hand I was interested in Sunset Overdrive, Dead Rising 3, Forza Horizon 2, Rise of the Tomb Raider (Yes, Timed exclusive, will probably sell better on PS4 when it releases, blah blah blah, I wanted to play it and didn't want to wait a year).
I guess what I'm saying is better 1st party doesn't equal better exclusives. Only 1 of the games I listed for MS were first party, and as far as I know Turn 10 isn't owned by MS. On that note, I actually don't know what exclusives for PS are 1st party.
LBP isn't Sony, Infamous isn't Sony, Bloodbourne isn't Sony.
Mind my ignorance, I'm learning. I didn't know Naughty Dog is owned by Sony. Apparently Sucker Punch is also owned by Sony. Oh my. Apparently Media Molecule is as well. The more you know *twinkle*
Seriously though, I thought all of those studios were independent like Kojima Productions, just with tons of exclusive deals.
