Universal Extractor because it is extremely useful for opening archives, and that's all it does.  As the name of the app implies, it only extracts...it can't create archives. Despite this, it's a neat little app to have in your Windows right-click menu.

You never know what kind of compressed file will come your way, and the developer claims that UniExtractor open any type of compressed file available.  So whether it's a ZIP, a RAR, a TAR or a JAR, UniExtractor claims to be able to handle it with ease.

The user-interface (such as it is) is a little on the spartan side.  The box is tiny, and the available preferences are nearly nonexistent. That said, it opened every file I threw at it. Having UniExtractor installed on your PC will enable you to uninstall all other compression software if all you need it for is to unzip files (and not make them).

My only complaints are that the website gives no system requirements and the developer is unresponsive. Universal Extractor definitely works on Windows 7 and Windows 8 desktop, but for anything older, you'd better make backups before trying it.

Note: The Download button takes you to the vendor's site, where you can download the latest version of the software.
