In all fairness, unless Windows has vastly improved, a standard retail copy of Windows is lacking in all but the most basic of hardware drivers and doesn't even have an equivalent to the non-free firmware version of Debian, forcing anyone in need of doing a clean install who doesn't have an OEM edition compatible with their system to manually download and install drivers from the website of each hardware vendor. Every install I've ever done of a Linux distro, be it Debian or otherwise provided better hardware support than every non-OEM install I've ever done of Windows, and honestly, the non-free firmware images seem to be unofficial only in so far as Debian only claims the free image... heck, I'm almost willing to bet real money the two versions are compiled and uploaded by the same people
And considering how many "everything but the kitchen sink" distros there are out there, I'll take Debian defaulting to a base system and then installing the extra software I want via aptitude over a distro that bundles many gigabytes of stuff I don't use and then have to uninstall if I want to keep the time to create/restore system backups reasonable.
