[Fedora] Out of patience with Ubuntu; help me pick my new OS?

http://ubuntuforums.org – For some reason, it seems that Ubuntu and I just weren't meant to be. Today marks the second time that it has crashed on me, completely out of nowhere, and refused to boot to the point that I have to boot from a Fedora live CD to even be able to use my computer at all. So I am seriously considering switching to either Debian itself, or to Fedora 16, which is what I'm posting this from. I've used Debian and Fedora temporarily in the past, so I'm somewhat familiar with both already-- mostly, I'm just wondering if one will present fewer problems than the other, given my particular usage habits (Hardware)
