You get a 70 MB "Ardour*.run" file that is a bash script that contains setup instructions followed by raw binary code. And you good the feeling of knowing that you've supporting a great open source project. Also note that only a few linux distros are bleeding-edge (such as Arch-Linux, which will contain binaries for newly released package versions pretty quickly). But if you are on a non-bleeding edge linux distro, your distro's repos aren't kept up-to-date and so the advantage of the Ardour binary download is you get an up-to-date package without having to install a 3rd-party repo or build it yourself.
