What phone should i buy?

I was thinking about waiting for the new Google Nexus Prime, but i hate the way Samsung makes they're phones. all plastic and cheap looking, i gotta hold it before i say no. then i heard of the HTC Amaze 4G. I'm an HTC person. the phones they make are beautiful (some of them). or the Apple iPhone4S. I've never had an iphone so i don't know why people love them so much... they all look the same to me. i'm in the battle between those three. i need someone else's opinion. before i buy something i wont like.What phone should i buy?
Had a Samsung android phone, it was cool until the software updates began to 'drag' the processor %26gt;_%26lt;

HTC phones are very functional, but they are android phones too which require periodic server updates. %26gt;_%26gt;

I got the iPhone 4 (never had one before) and I have to admit that "I'm Lovin' it!" The usability, interface and the app market are much more steam-lined than the android. All the perks like face-time, camera, itunes, etc were all designed with the cell phone user in mind!What phone should i buy?
Amaze 4G is a 4G device, so it's better than iPhone 4S when it comes to speed, but UI wise, iPhone 4S is better.What phone should i buy?
An iPhone or a Blackberry,
