Does it do anything more than Apples Archive Utility?

While I’m glad this is free, I don’t see it having any more functionality than the Archive Utility that is already included with Mac OS X. I couldn’t find any documentation Granted the Archive Utility is hidden deep in System > Library > CoreServices > Applications so it is a bit harder to find, but it automatically runs when needed. The Archive Utility can compress as well. What benefit does this bring other than something that is easier to stick into the dock?
