What do you want to compare? Performance? Features? Something else?

What is your definition of "real" Unix? Ultrix is sortof a 
BSD-derivative. I hope you understand that.

The problem with Ultrix is not documentation, but the fact that it is 
somewhat different than other Unix clones you might hit upon. Back in 
the 80s this was a more common phenomenon. Every Unix system was 
slightly different.

This is why tools like autoconf got created - because it is a pain in 
the butt to make software that runs on all different styles of Unix. In 
todays world, Ultrix is very different in many ways compared to Linux or 
modern BSD. And most people have even stopped trying to keep things 
working properly on other flavors of Unix.

So you will probably have to do some hacking and fixing of your own in 
order to get any software to run.
Welcome back to the 90. This is what everybody did back then.
