Desktop ready?
For many years (since the mid ninetees) I try each and every release of the major distro's, including Fedora. Yet for desktop users Fedora still isn't the thing to advise. Ouf the box less hardware works with it and less software (and particularly multimedia too) works, making it more difficult for users who just want to use it.
The mentioned configurability (being so great in the Fedora installer), when's the last time you tried Slackware for example ?! I know this is not the most common adopted Linux distro, but I still like it nevertheless.
Personally: for most people Mint Linux works best out of the box: no distro has more hardware working out of the box (and yes: this makes use of proprietary drivers sometimes, so if you don't like that this is not the distro for you), but mostly (as a PC user, not a hard-core developer) it is the only distro to have all media codecs etc in default install to play just about any media that is out on the Internet... easier then that it not possible. (it also has some nice tools for doing certain taks)
