What's a good smart phone to get that's NOT the iphone?

I got an iphone 4s as an upgrade and I'm NOT happy. I got it about a year and a half ago and I can upgrade soon in a few months. I don't know a lot about smart phones.

I want something reliable, doesn't freeze up as much and isn't a delicate, fragile device that shatters after a two foot drop.

I want something that allows me to have music with a set of practical apps, not so much games. Any suggestions? My friend won a galaxy III in a contest and is selling it for 100 dollars.
I also thought of upgrading to the Droid razr in a few months(6).

Get a droid razer maz hd. Don't get a samsung galazy as they break easier than an iphone.

I have a Galaxy SIII and I love it. But comparing the apps to apple, I prefer Apple's apps, they're more useful.
