Use injection. The difference is that there is no way to override the implementation of the static accessor / singleton for testing functionality. If you instead use an IoC container (Spring / Guice) and injection, you are not statically tying yourself to a single class. Work off the interface, and all the places in your code that use that interface can be changed to use a different implementation without changing each of them - just change the config as to which one is injected.
