Personally I'm going with the Xbox and its simply a matter of trusting Microsoft's software over Sony. Yes the PS4 has slightly better hardware but I think Microsoft optimizes their software better to the hardware. Just watch for the problems that will arise with multi platform releases like Battlefield 4. It took Sony well over a year to fix the lag input issue that some players experienced with Battlefield 3 on the PS3. It came down to who had the more optimized software and not the Blu ray player that made for a better gaming experience. I'm a battlefield fan boy if you can't tell.
I have both platforms btw and find that as fare as multi platform games go I do have a better experience with Xbox so far. I will admit that Sony gets the rights to better console exclusive releases for the most part. I guess it comes down to what type of gamer you are. If you want the best multi player experience go with Xbox, if you're a solo gamer that wants a better single player experience go with the PS4.
You know all those problems are associated with the very different architecture Sony chose for the PS3, right?
Like a very powerful processor but a rather weak graphics chip [originally, they did not want to have a GPU at all] and the not so ideal RAM share distribution [256 + 256, apart from Xbox's 512 chunk]
It was ultimately very difficult to utilize by 3rd parties as the Unreal Engine and other engines were simply not ideal, which is evident when a custom tailored engine was created for every and each 1st party game, which proved that when utilized right, PS3 was as powerful if not more than the Xbox 360.
Just look at The Last of Us and Beyond: Two Souls, etc.
For multi-platform releases, 360 proved to be the easier platform to work with and most of the time the games were ported to PS3. While every time PS3 was chosen as the lead platform, the game looked better on it, which was not all that often.
With the PS4, Sony realized their mistake and are doing all the right things to fix it. As a matter of fact, PS4 has been confirmed as the easier, more powerful and better platform to develop for by the developers themselves, not even talking about 1st parties.
It had very little to do with Sony's OS, mostly it had to do with the unfortunate choice of architecture, which has been corrected this time around.
If you want to talk about software, the Microsoft's XBOX ONE graphics drivers are working only so-so, while Sony's seem to be doing quite fine + MS is sticking with 3 OS. 3 operating systems for 1 console. Does that sound easy to you?
If you search a bit around the internet, you will find the very information I am posting right now. So next time, please get your facts straight.
Thank you.
Ultimately, Xbox 360 was the platform of choice for developers and deservingly so. This time everything points at the PS4 as the platform to use the most.
Hope this clears it up somewhat.
