There are lot of new features in JDK 7. Of course the latest versions always are better than the previous ones and its wise to go with the newer version

Few which I could list- Strings in switch and other
java languages enhancements in Project Coin, Automatic Resource management- you need not worry about closing the resources (file streams for example). The forum which I mentioned in the previous post has a few discussions around Java7/8
