https://www.youtube.com/watch?v=EMIptqMaym8 Found this interesting video that shows the speed and delay of opening up apps on both the Note 4 and the iPhone 5S. The iPhone 5S is clearly faster and it's things like that which makes me want to go back to Apple after having owned several Android devices (like all the 3 Note generations) the past three years. Apple just offers a smoother experience with their optimized software and hardware. For some people those half to two second delays aren't important but for me personally it is. There are also other speed test videos comparing the LG G3 and HTC m8 to the Note 4 and they too are faster than the Note 4. https://www.youtube.com/watch?v=OV8_ESdKoD0 https://www.youtube.com/watch?v=1OIT0pC6W98 Notice in the comment section of those videos how the Samsung fanboys are in denial making up all kinds of funny excuses.
