Slackware.
This isn't even a comparison! You're into hacking-n-stuff, and I KNOW you're a geek and like to configure stuff the hard way (oh HTML in Notepad boy

).
Slack lets you do that. I use it. Won't use anything else. Will advise everyone else to use it.
Found a pretty good way to choose a distro, though.
Check it out:
If everyone you know is running a particular distribution and you are a newcomer, use the same one they do.
If you like to roll your own--that is, you expect to compile and install everything yourself--Slackware is probably for you.
If you want to ``go with the crowd'' today, install Red Hat.
If you want ``everything'', install S.u.S.E.
If you need the most ``commercial'' looking product or you are a VAR (value-added reseller), pick Caldera.
If the politics of free software is important to you and/or you want to get involved in development of a distribution, pick Debian.
If you have a bunch of systems you need to interconnect and upgrade, pick Debian or hope Caldera gets COAS completed.
I think TechGuy falls under the slackware category!
