Well, all of my computers are multiboot (and I mean that! - not dual-boot Lin/Win). But my main desktop everywhere is Gentoo. I've chosen it, or maybe rather I've stayed with it because of the
learning factor and
hands-on approach. Another reason is that in Gentoo I really can make everything work, it's just a matter of reading/tweaking.
My first real Linux was Debian at work, where I installed it on the Sun hardware. A lot of learning, cursing, trying, etc. But it made me brave enough to try something else. From what I recall, I always wanted to do a Linux From Scratch installation, but I never had enough time. Then I've tried PCLinuxOS (and I still prefer it over Knoppix), Debian/i586, Ubuntu and finally Gentoo. And that was it! I've started with 2004.0, and since then I've installed it several times, every installation being successful and better than the previous. Finally I've screwed everything (or maybe I only thought so), reinstalled it the last time - and it just sits there and works. Now I have a habit of being a bit conservative (read: more careful) with updates.
So my machines have:
#1 (desktop@home, Athlon 64):
- WinME => gaming
- WinXP 32-bit => for Canon printer
- WinXP/x64 => free beta, for seeing what it can do
- Gentoo/amd64 => my main desktop
#2 (desktop@work, Athlon Thunderbird):
- WinXP 32-bit => compatibility with my work environment
- Gentoo/x32 => my main desktop
- Gentoo/x32 => a trial ground
#3 (laptop, Turion 64):
- WinXP 32-bit => it came with it, so I kept it anyway
- Ubuntu 5.04 => just a stop for installing Gentoo

- Gentoo/x32 => my main desktop
- Gentoo/amd64 => my trial ground
Gentoo is addictive, that's all I can say. And I still learn something with every update
