Spec me a distro

[uniQ]

I'm studying Forensic Computing and several modules are heavily based on Linux.

For Forensics I've installed:

Backtrack 5
Fedora 17 Security
DEFT
Helix

But I'm also looking for a 'regular' linux distro to use on a more day to day basis.

So far I have installed as VM's:

Mint Cinnamon 13
Fedora 17
Ubuntu 12.04

Of these so far I like Mint the most aesthetically, I'll probably grab OpenSUSE as well and give that a spin. Any other recommendations?

Thanks for the suggestions. Downloading Arch now.
