Which is better, iPhone 4S or droid razr M?

I'm looking to upgrade my current phone (a flippy little free thing) and I'm trying to decide between the two. I've had an iPhone in the past, and I know how to use it, but I'm still unsure of which is the better phone for me.

If you want a phone with minmial features that has apps you download get the iphone. But if you want to be costimizsiable then get the droid razr

The iPhone 4s is faster and will just work better over all, the droid razrrm is made of cheap plastic and sucks.
