After going back and forth between iOS and Android for a few years now and ending up with a 5s for now, I am thinking the big difference (for me anyways) is the hardware. I just had a chance to really test these out again recently with the LG G2 and my 5s for a week. A few examples of this would be: Build quality-Better on the iPhone than most Android phones Ive owned. Especially the earpiece and speakerphone. Camera-Again, better than most Android phone Ive had. This is especially noticeable with video recordings at events like a concert. The iPhone picks up the sound (even the vocals) exceptionally well and plays it back clearly. Any Android phone Ive had records the audio like a mess. It just sounds like a ton of noise coming from a blown out speaker. Radios-For some reason, with my 5s I can get LTE in places around town I never could with any Android phone regardless of manufacturer. The GPS is also extremely accurate and locks in instantly. Ive actually had to pull over in my car in an area I didnt know and wait for GPS to lock while using navigation on my S4 for several minutes. Once, I had to actually restart my Note 2 to get the GPS to locate me, never has this issue with the iPhone. Wifi-Despite having an inferior wifi setup compared to a few Android phones, my 5s gets a better wifi signal. My home wifi is picked up by my 5s even 3 houses down whereas my last few Android phones would drop the signal by the time I hit my sidewalk. Not only that but when I am closer to the router, the 5s uses my main connection but when I go to another side of my house, it automatically switches to the stronger signal from my wifi extender. Something no Android phone I had ever did. I really like a lot of the freedoms Android offers software wise, but I just havent found one yet that matches the iPhone in any of the above areas I mentioned. Having said that, I have yet to use a newer Nexus phone. Last one was the Verizon Galaxy Nexus, a truly awful phone. If the Nexus 5 has LTE and is available on Verizon, Id strongly consider it.
