I voted for iOS! I don't have an iPhone, but I do have an iPod 5 and a Samsung S3. I love my iPod and use it for almost everything, but the S3 drives me crazy. The notes feature is dreadful, using the Internet is a nightmare, the controls are extremely frustrating, it only has like one font it can ever display, and the lowest volume I can have one of the preset ringtones on is deafening (plus the lowest volume setting is pretty loud when it comes to things like YouTube as well). Both devices restart randomly at times, but my phone does it much more (but that may be Pocket Camp's fault as it seems to happen more often when I'm using that). I have a few complaints about my iPod as well (lately the touchscreen has been acting up occasionally and sometimes my browser tabs disappear), but other than that I love it; the displays are much nicer than on my Samsung, it's way easier for me to use, and I've put it through so much abuse (dropping on hardwood floors, throwing it at walls, etc.) and it's still in perfect condition minus a couple of scuffs on the back.
