Need to get a smart phone. What's good?

For what its worth I have had my iPhone 4 for a little over 2 years.. its the best phone I have ever owned.. Never had any issues with it... battery, talk, or web wise... Now the iPhone 5 is finally here, I will probably have to stick with the 4 for at least a year (until the price of the 5 comes down a little... the price for it is way to steep for me.. )..
