you have to note that on Debian mate-environment-extras (Gnome2) is running and on SUSE Gnome3 GUI is running… no GUI on CentOS.

it is interesting to see what kernel+filesystem the distributions rely on.

Kernels:

While CentOS is still on 3.10, Debian is believing in 3.16, and SUSE is „latest“ with it’s 4.4 Version kernel.

you can upgrade with Debian to 4.X with: https://unix.stackexchange.com/questions/305172/upgrade-linux-kernel-3-to-4-in-debian-8

Filesystems:

Its very interesting that CentOS and SUSE rely on xfs.

Debian is relying on ext4… while ext3 might be a little bit slower but even more solid. (that’s what you should use for your NAS/FILESERVER)

Debian Package mate-environment-extras + lightdm

SUSE Enterprise Server 12 + Gnome2 (?)
