Your association isn't really accurate. 1Password's storage model is basically the same as KeePass, your passwords are stored in encrypted blobs that are not decryptable without your master password, which is never sent over the network even if you use their completely optional cloud storage and web interface. If you don't want to trust them with even your encrypted blobs, it also supports sync via Dropbox or iCloud, or over wifi to your phone/tablet, or just to a plain folder. As far as advantages, I'd say that 1Password is a very slick and well-designed password manager that focuses on covering a particular common case - someone with a Mac, an iPhone/Android device and possibly a Windows PC who wants to sync their passwords between those devices and fill passwords in their browsers. It offers first-party supported browser extensions and handles conflicting sync changes well, which were two major pain points for me when I used KeePass. If you're happy with KeePass, there's not really a compelling reason to switch. If you fit their target audience and want something with better sync/browser integration and/or a better Mac client, I think it's a compelling alternative.
