For me I chose the Desire over an iPhone because it appealed to the nerd in me, the ability to tweak to your heart's desire won over the polished but controlled nature of the iOS. In terms of design aesthetics it's a toss up as they say beauty lies in the eye of the beholder. Apple to be fair makes excellent products that work out of the box most times and their user experience IMHO is still the one to beat, notwithstanding my choice of Android. However, the Android platform is incredibly vibrant and the inherrent potential therein is the one thing that excites me more. At the end it's up to your individual preference.
