Which one is the Smartphone for me? HTC One? iPhone 5?

Hey guys,

I've been a bit out of touch with recent developments in Smartphones and I would hope you could help me out.

My current phone is the first iteration of Samsung Galaxy S, running Android 2.3.3. I haven't exactly treated it nicely, it has survived more plummets than you could expect it to, but the battery is slowly dying on me and recently it has a habit of not recognising the SD-card.

I tried both Android and iOS on tablets before. Android seemed to be high-maintenance and really ugly, iOS exasperatingly restrictive.

At any rate, I'm in the market for a new phone. I have used the old one mostly as an MP3-player, GBA-emulator and to read and shoot short e-mails.

A killer feature on the iPhone would be iRig. This alone would sway me in the iPhone's direction, but the HTC One would be a reasonable media consumption device that could make me get rid of my tablet entirely. Then again, I primarily use a Mac.

I'm just thinking out loud, maybe you guys could help me out.
