Mac is actually just a version of Unix. Which they all are technically. So you query should be your favorite version of *Nix. Plus technically you cant include OS X cause it doesnt fall under the Linux GPL license nor does it use teh Linux/BSD kernel. Which is what is at the source.
I would say that with my limited experience Ubuntu. I have tried PCLOS and didnt like it at all.
Okay now here is my question. What is the difference. Looking at their site i see Fedora, KDE Fedorea and GNOME Fedora. I am guessing that Fedora is rpm package based, Gnome is like Ubuntu and deb package based and KDE is like PCLOS. So which package to go with? So lost and confused...
Well i am used to Gnome cause of Ubuntu. But i am grabbing both the Fedora and Gnome versions. I will use the LiveCD to see how i like it then i will use part of the 98GB i ahve free and make a spot for the distro and install it.
Knowing me and the limited Linux experience i have. It will probably be the Gnome version since i already have experience there and know what to do with it. But i wont put down the regualr version since i have heard many great things about that one as well.
I don't know, I've been using both, and I got used to both, thats why they are the same in my eyes. Both are pretty nice to work with, in my opinion. I'm sure at least one will suit your needs perfectly.
Even though in theory Mac OS X isn't a "distribution", it is based on a rich UNIX core with full command line access, combined with a beautiful, fluid user interface, and it's also one of the more widely spread UNIXes today, so I'm voting for OS X.
