Even after a year and a half of it pretty much being an extension of my hand, I'm still amazed by how gorgeous my 4S is when I take the case off.
 
5. Looks like a piece of expensive jewelry (the white one). Feels great in the hand and the screen is amazing.

4S is nice too. Actually an amazing phone still.
 
The 5 has been my favorite do to the total lack of problems i have with it and of course the speed.
 
3GS was my first iPhone and it was a revelation!!

However, iPhone 4 with the all new design and first taste of a retina display on an iPhone absolutely blew me away.

iPhone 5 has really impressed me too. An improvement in every regard and I must say, my favorite rendition of the iPhone.
 
3GS because it was so comfortable to hold. Yeah, the back was plastic but it had enough glass and metal bezel that it felt premium. Also was my first iphone experience, the cool square box, downloading first apps. Miss that thing.
 
iPhone 4 because it was the biggest iPhone upgrade ever. Not only had it a radically new design, but the iPhone 4 also had so many new features compared to the iPhone 3GS.

Most importantly, though, the iPhone 4 had - at the time - unique features, like the Retina display.
 
My personal Favorite was the 4, just because of what it brought to us from a smartphone point of view, the screen, the look and feel etc.

I have had every model since the 3G to the 5 now
 
3G/3GS. Sat comfortably in the hand and since it was plastic never had to worry about babying it
 
I love the look and feel of the 4 and 4S, but the fact that it keeps sliding off almost any surface annoys me, and I like the bigger screen of the 5, so I would have to say the 5 is my favourite so far.
 
4 since it was very advanced for its time and had the good old bitmap google maps.

The 5 is a lot more advanced then the 4, but the competition at the time of the 5 was much better, making the 5 not much of a leap over phones from its era.
