Upd: I use Debian on my servers and vps's and have no idea why people still choose CentOS for their servers. C'mon guys, Centos' default repository lacks lots of necessary stuff, such as nginx. You just have to plug in 3rd party repos and turn your system into a mess. It has RHEL as upstream with all that lawyers stuff related to huge corporations - such as the case when CentOS had crippled OpenSSL without elliptic curve algorithms because there were some obscure patent problems. Why not Debian? Is it because CPanel works on Centos only? There are other panels, and anyway, vanilla ssh console is almost always faster way to do things.
Big fan of Manjaro myself although Elementary OS has a nice feel and UI.
I don't like Ubuntu 13 either, Unity sucks. My home system is a Win7 where I run Virtual Box and switch between Ubuntu 10.04 LTS or 12.04 LTS for general Unix plinking around. I have two VPS systems where on one I run a LAMP stack on Ubuntu 12.04 server for Prosper202 tracking software and on the other I run Centos 6.4 for Zpanel hosting.
I prefer to you CentOS 7, minimal, command line interface! It is easily hosted any where, on a server, on a desktop or in a VM; it just works! Plus, there are no slow downs unlike in Windows and sometimes even OS X.
I stopped using Linux for a while, after I started doing more Photoshop work, where Gimp just wouldn't cut it. I'm keen to start checking out distros again, I know there's gonna be at least a couple of updates since last I checked.
