Proud Samsung galaxy owner and I say screw the iPhone. It's the only Apple product I dont own/support. Quality over brand. Better camaraderie, loom
ks better, and is more user friendly. Another thing is I got more compliments after I switched to the Samsung galaxy.
iPhone is much better quality in both casing and software.
And Android more user friendly? That's a joke.
Samsung is a joke nowadays, their convoluted hardware configs are a joke, which get bested by physically inferior setups thanks to having made better use of the power. Technoobs be shouting "Snapdragon gunna be soo smooooth" not knowing Snapdragons are cheap, mass produced, underwhelming chips no matter the guise.
Add that to the fact that Qualcomm are just an cheapass-company that make poor hardware (*cough* Atheros *cough) that never lives up to it's promises - Snapdragon S4 Pro was supposed to the one to beat and apparently that was meant to taken literally, as all it's competitors blew it out off the water - and you start to figure out why Samsung gets a small return despite huge marketing efforts.
If the OP is going down the Android route, he should consider LG G3, HTC One M8 or Sony Xperia Z2.
If the OP is going down the Windows route, he should consider the Nokia 930.
iPhone 5S speaks for itself although the iPhone 6 will soon be out.
