Better phone on Tmobile-iPhone 5 or HTC One?

I can't decide!

Added (1). I've had android phones ever since I got my first phone.

IPhone 5

The HTC One is arguably the best Android phone available and bests the iPhone 5 in several ways. IPhone users who are on the fence between upgrading to an iPhone 5 and switching to Android should take a close look at the HTC One. Its excellent design and build quality is something users must see in person to fully appreciate.

IPhone 5 since T-mobile at the moment has the fastest LTE network in the US

Whichever attracts you the most is the better phone.

HTC One is a great phone and android is a great OS

HTC One is very good phone and I can guarantee that you will love it. It has all the things an iphone has but better. Obviously it is newer so it will have better specs but here are some of the basics,
HTC One has a 1080p screen which is so crisp and clear, you have to actually look at the phone to know what i'm talking about.
It also has the full aluminum body which is way better than the iphones, and not just in looks but when you hold the phone it has a nice curve which fits perfectly into your palm
Has an IR blaster meaning you can use it to control your tv.

I'm assuming that you had an Iphone before this. I have seen so many people who switched from an Iphone to the HTC One. I personally think that people see the all aluminum body and know they want it. I do have one friend who got the Iphone 5 instead of the HTC One and he liked the phone but he wished he had got the one instead. Also HTC=open source android where it is much more customizable and if you want to download something from like a web browser it will still work.
And Iphones=closed simplistic IOS which means not nearly as customizable or free but in exchange you do get a nice clean user interface but it get's really boring for a lot.
