Gentoo, Funtoo... There's a few others but I don't remember their names.xubuntu is probably the only ubuntu derivative that balances everything right without tons of bloat. you could try out crunchbang too I guess.
Arch is it's own little "bubble", completely unrelated to Ubuntu in every way and pretty much every other linux distro, aside from the fact that they both run on Linux.I don't want to sound like an starfish, but do you know what you're doing here?
