I always tell people that I think they will like either choice. The vast majority of games people are playing are available on PS4, Xbox One, and PC. Sure, many of the multiplatform games that are 1080p on PS4 are 900p on Xbox One but if small technical differences are that important to a person they should probably be playing on PC anyways. I can honestly say that I can't see the difference between 1080p and 900p when a game is in action but some people claim they can.
It really comes down to a couple things. Do you prefer the exclusive lineup on one console over the other and do you have a more active friends list on one console than the other?
For me the answer to both of those questions is Xbox One for the most part. I have a couple college buddies who play COD on PS4 every year so I always buy COD on Playstation. That and Madden are literally the only series these guys play though. The rest of my friends and family who play video games play on Xbox One.
As for exclusives, last gen I thought the PS3 won but it was close. They just had so many more offerings with much greater variety. The 360's exclusives were great and they were much bigger releases but they were mostly shooters and there were much fewer of them.
I think the Xbox One is easily winning in terms of exclusives through this holiday season. I played Killzone but inFamous Second Son and Rocket League have been the only exclusives I actually cared about so far. I really like Until Dawn so far and and I'll be getting to the Uncharted Collection at some point. I think this will start to turn around next year with Uncharted 4 and Horizon but I think the PS4 exclusive library has been pretty weak so far.
The exclusives I have personally played, and liked on Xbox One are Sunset Overdrive, Forza 5, Forza Horizon 2, Titanfall, Dead Rising 3, Ryse: Son of Rome, Smite, Master Chief Collection, Gears Ultimate Edition, and Halo 5 comes out next week.
PS4 might have started as the gamer first platform with that terrible E3 announcement Microsoft had. That's not what the Xbox One actually turned into though. Phil Spencer really turned the ship around when he took over. Between the Xbox just having more exclusives and backwards compatibility I would argue that the Xbox One is actually the more gamer friendly platform right now.
I don't really even use the multimedia functions on either console very often anymore and I still use my Xbox One much more often than my PS4. That being said, I still stand by my original point that most people would be happy with either console. Multiplatform games make up the majority of what most people play and they are basically the same no matter where you play them.
I also think things are going to change on the exclusive games front for Sony soon. On the other hand, maybe they think they don't need to invest as much money into exclusives as they did when they were trailing the 360 most of last generation. I think I read that the PS4 has outsold the Xbox One in all but one month since the consoles have been released and that is even with the lack of exclusives.
Edit: While I was typing up this incredibly long winded answer
yourbeliefs basically provided the same information in a more succinct post. It looks like we agree on most of this stuff.
I also agree that Xbox Live is more reliable than PSN for online gaming but I wanted to point out that I think the free game offerings have been a little stronger on PS Plus.
