First of all Linux does not represent all UNIX.infact GNU/Linux is a UNIX-Like Operating System.and to carry
UNIX trademark u have to comply ur OS with *www.opengroup.org standards and pay them for the license like apple did for OS X.
GNU/Linux is the best UNIX-like Operating System as of today because of its Open Source architecture+the popularity and the support for the hardware and other extra features.
I'd have selected FreeBSD;but the community is themself locked and the distro are not novice-friendly imho.
the worst UNIX ever made is darwin which is a messy codebase which is OS X of mac
![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
OS X is sinking the good name of UNIX coz of the dirty hacks it uses to call it "idiot friendly"
Personally,I dont find Debian geeky and Ubuntu is just a small drop taken from the debian pool!I will always stick to Debian which is the best distro any time!

note that it requires a "used to *nix" user to switch to Debian.
FOSS nature of GNU/Linux is the basic cause of success.the organized way with a "lead" Linus who keeps the kernel fresh and neat and removes dirty hacks as much as possible.
One thing Linux kernel misses is a uniformed kernel API for developers to write drivers.this is due to different drivers which are needed to be corrected and devels are not interested at this moment I think.
Solaris(Open Solaris) is one good alternative UNIX which is growing under the lead of Ian Murdock(founder of Debian).We may expect a good OS with Open Solaris in some time(remember,Project Indiana),I hope.
Just read a week or so back that forefather of UNIX,Multics is released under FOSS license!wait and watch if some thing good turns out
![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and even read that multics is inherently superior to UNIX OS's.
