I know you'll be getting lots of thumb downs from the community but it is the truth. For some reason the iPhone has the best games, best looking, and best functioning games out there. I've tried some high end games on the android market and so far none seem to offer the caliber that the iPhone can put out. Almost the same when it comes to apps.And what reason is that? The best games and support are on the iOS platform, that cant be disputed. If you never had an iPhone, then dont talk.
I can't vouch for the moto gui, but i do like the HTC sense gui. the gui in general is by far better than stock iPhone. Having custom widgets allows me to focus on what i want to see first on my android vs shuffling through page after page after page of iphone apps to get to my radarnow program.Cydia allows you to do alot with your iPhone. Droid users have by default the GUI that Motorola puts on it. In order to really use your droid, you have to root it as well.
