Wow, this is going to be my first post in a while. From experience with owning both the OnePlus One for about 4 months, and the Note 4, which is my current daily driver, I would have to admit this. I'd rather use the OnePlus One due to the immensely better battery life. I have to carry a battery pack with me nowadays due to constantly using bluetooth and reading Reddit, and I get really close to draining the battery on it. With the One, I never had that issue. I also find that the One is much more ergonomic in the hand compared to the Note 4 due to its radiused edges. Regarding the 1440p display, yeah, there isn't a night and day difference. At normal viewing distance, you're not going to really notice the difference unless you look for it.
