Main Operating System (Score 1)

I use to use Debian exclusively but in the past year I have switched to Arch Linux. The rolling upgrades do not break the entire system whereas Debian has a very long time between release upgrades. Upgrading to a new release has caused me problems in the past. Now Arch Linux is constantly upgrading and sometimes something gets out of whack but you can always downgrade one package without having to install the entire system.

By the way I still have my Hamm floppies :-)
