I know the love of iOS. I tend to defend it when the blind fanboys / apple haters post inaccurate info about the phone.
The M8 and S5 are hard phones to switch to if you like iOS. I know, I have tried every phone on the planet ( /s )
I love iOS, but I truly Hate the tiny 4" screen. I will disagree that its "not much difference"
I will be one of those the return to iOS when the 4.7 or 5.5" iPhone 6 hits. but for now, you couldn't pay me to use an iPhone 5s.
The Moto x IS the iPhone of the android world. Sooooooooooo comfortable, 4.7" screen, hands free goodies, smooth, fast, and NO TOUCHWIZ or sense 5 or 6 or whatever number HTC is up to now.
Of course the X+1 is due out soon (tm), so holding off and seeing it and the G3 might be a good idea.
After trying many android and Windows phones and going back to iPhone more times than I can count, I have finally settled down with the LG G2 and its awesome.
It's 5.2" screen but nearly no bezel at all, and its gently curved on the back and it makes it feel like a dream in the hand.
I don't use cases at all, but I watched a co worker miss his pocket and dropped his iPhone 5s from 30" off the ground and it too got spurs and mangled the aluminum pretty badly.
I love switching and trying every phone I can, but even I didn't bother with the M8 after seeing it in person, and I fell in hate with touchwiz after owning a few android phones without it. so that makes the S5 a non-option for me as well.
LG has become my favorite OS that isn't Pure android like Nexus and Moto x (moto x is 99% pure android, with 1% additional awesome)
Enjoy the iPhone, it's a great device. Android isn't for everyone, just like Blackberry and Windows Phone. No harm in switching phones to find one that fits your needs and wants.
