I found this Linux distribution that has an idea that it needs to be based on Gnome 184.108.40.206 forever. This distro is called Fuduntu. The advantage of this is you can update all the programs, kernel, x.org, drivers. Gnome 2.32.2 is just reliable, not buggy and PC-BSD Gnome is based on 2.32.2. PC-BSD 10.0 is going to go with MATE 1.x after Gnome 2.32.1.
I would rather go with Scientific Linux 6.3, because the kernel is updated off the best commercial server. SL 6.3 kernel has many kernel 3.3 features anyhow.
I believe Scientific Linux 7.0 should be based off MATE 1.4 or MATE 1.6.
