you are (deliberately?) elusive with your question so Laslo was
(deliberately?) elusive in his anwser. nevertheless,
he already replied. so i try my way:

you can compare those two OS only thru perspectives.

* linux is a unix clone (so flaws in the design, including symlinks)
  are cloned too.
* linux is a side project that became the most used unix kernel of
  the world, supporting a lot of hardware and providing a stable
  ABI no matter what (thanks to linus's opiniated point of view).
  so yes ... it has history and this shows on the codebase.

plan9 was a research os to fix the design flaws of unix but
didn't evolve that much since it was abandonned then publicly released.
so ...

* design and code are much more cleaner and consistent and remained
  that way.
* tools are probably the state of art of 90's
  (good starting point to reinvent the computer tech because
  everything went terribly wrong since then)
* on the other hand, it works on very few hardware and lack of
  tools for modern usage.

the question is: what do you need to compare them? what's your goal?
if it's considering using one or another, that's the way i would use

* as a deskop os on tiny hardware if you don't mind the lack of tools
* as a virtual machine in a qemu to provide distributed services

also when i talk about plan9, i think about recent evolutions of it
like harvey os or 9front (i have to admit i don't know about the

can you be specific ?
