Coming from someone who had an Xbox 360 and decided to switch over to play station for next gen, I find psn annoying. The interface is annoying, and you can't even change your psn name once you choose it. You said you weren't really interested in the online though. I personally prefer the unique Xbox games as well, so I regret getting the ps4. As for durability, I haven't had any problems with my ps4. It runs smooth and never really overheats. Xbox 360 is notorious for shitty technical problems (red ring), but I'm not sure about Xbox one.
In short, I prefer Xbox, but in terms of durability and efficiency ps4 may be the safer choice.
