First and foremost, go where the games are. If you like Playstation exclusives pick up a PS4. If you like Xbox exclusives pick up an X1. They are both great systems.
I don't own a PS4 yet but I will soon. I've had an X1 since launch so I can give you some thoughts. Your two listed pros, are also two of my pros. Instant game resume is pretty freaking sweet, snapping apps is useful if you have a large enough TV and quickly switching from say Netflix or your TV channels to a game is great. As far as voice commands go, I use them a lot for tasks outside of gaming. That being said, there are a few times where I will be using voice commands and I will have to pick up the controller and select something...kind of ruins the point of voice commands. On that same note, other than voice commands, I don't really use kinect at all but I do think it's worth it for voice commands. If you are on a tight budget, I would actually suggest picking up the kinect-less version.
Something else that the Xbox is killing it at is system updates. Every month they release fixes/new features/updating the user interface. I'm not too familiar with the update process of the PS4 operating system but I do know the updates are not nearly as frequent.
Of course, this comes down to preference but I do enjoy the X1 controller much more than the PS4 controller. To be fair, I have also used the X1 controller a lot more than the PS4 controller.
You mentioned free games with PS+ and I would definitely agree with you. With Xbox Live Gold you also get free games but I personally think the PS+ games are better. Be that as it may, the Xbox Live Gold games are pretty decent...and it's still free games.
Another thing to think about is indie games. So far, and in the future, the PS4 is pretty much the go to indie console. In saying that, the X1 is going to be getting a lot of great indie games too.
You did mention the better looking games for the PS4. That is absolutely true and will always be true. Games on the PS4 will almost always look better than games on the X1. Does it matter though? Will the difference be big enough for you to notice? Some people can notice the difference and do care about the difference but the vast majority of people who own these consoles either can't tell a difference or don't care. If better visuals in games is something that you really care about than yeah the PS4 would have you covered.
Something else that rarely gets mentioned in these types of conversations is company resources. Microsoft is a crazy huge company with virtually unlimited resources. You have people like Phil Spencer hitting the ground running with GAMES GAMES GAMES and distancing the Xbox team from the debacle of the X1 reveal. I can guarantee Phil has an ENORMOUS budget to work with. You also have the CEO of Microsoft publicly stating that the Xbox division and gaming in general is very important to the core business and future of Microsoft. This means lots and lots of money and resources are going to be and are being poured into the Xbox team so that the X1 is a success. On the other hand, you have the Playstation division doing great in a company that isn't doing so great. I don't know this for sure, but my guess is that the Playstation division or whatever it's called isn't getting too much support from Sony.
In saying all of that, what console would I recommend? Once again, go where the games are. If you like Uncharted, Infamous, Little Big Planet, Bloodbourne, etc. etc. go with the PS4, you won't be disappointed at all! If you like Halo, Gears of War, Sunset Overdrive, Forza, Ryse, Quantam Break etc. etc. go with the X1, you won't be disappointed at all! If you like all games equally, I would suggest an X1.
Edit: I forgot to add, consider what your friends have. If you have friend that play games and y'all like to play with each other than definitely consider that.
