There's some aspects to the iPhone that annoy me but I love mine (that's why I picked it in a poll because it's what I'd get) and if you're looking for one that has a simple UI, easy to use and looks good then get an iPhone. The only problem is that they're a bit pricey.
Android is good if you want to have full control over system storage (you can expand it etc.) and ones like the pixel and s7 (if that's an option for you) are quite good- however in my experience they're quite hard to get used to if you're used to the iOS on the iPhone.
Honestly I can't really be arsed anymore with the taking sides things and I'm not gonna lie, if I didn't have the connectivity to my Mac and if I didn't have my watch then I'd be wanting to have an android for once but it's really good with the Mac and the watch is a paperweight without an iPhone
Just choose what you think would make you happy and take some advice into consideration but the 'iPhones are crap!!!!! Don't use iPhones!!!' Posts And vice versa aren't things to look at/take seriously
