By reading tweak_epub's docs seems they are pretty similar. tweak_epub have some basic metadata editor, and it gives you a list of the files inside the epub. ExplodeImplodeEpub just presents you the uncompressed folder.
But it seems tweak_epub only runs on Windows, though.
It also lets you associate an external editor to be invoked to edit files - default is Notepad, I use Notepad++. It seems to be small, fast, and work well.
My usage so far indicates that it is a useful option for Windows users.
