A few weeks ago I bought an HTC Inspire, which I believe is the AT&T counterpart of the Desire. It's really good. However I compared it to the iPhone, not the Samsung, and it compared very well.
Not sure if this helps you, but compared to the iPhone 4, the HTC is 4G, has a bigger screen, a better camera, and a $100 lower price tag. I also went to Youtube to see a side-by-side comparison of those two phones, and at the end the reviewer agreed that the HTC was better. And in the comments below the video, all the HTC fans said stuff like, "The HTC is better because of this and this and this..." The iPhone supporters just said stuff like, "I love my iPhone." That's all they had...lame...so I bought the HTC and I am happy with it.
