Which linux desktop environment do you use?

I fell in love with linux just a couple of months ago. I was a hardcore Windows user ever since Windows 95. I have seemed to settle on Unity as my favorite desktop. It fits my needs the most as it maximizes my vertical pixels and the side bar is enough to provide ample space for most of my software.
Which desktop environment do you use and why?

 

I'll vote Xfce for my netbook, although GNOME, KDE, and Unity are also used in my virtual machines.

Do note that there should be an "Other" option: https://en.wikipedia.org/wiki/Linux_desktop_environments

 

Vote XFCE.
Is good for old pc.
LXDE is poor usable.

 

We need an "Other" option as I don't use a DE at all instead preferring a standalone window manager.

 

Sometimes I use Puppy Linux, no installation required, but it is no replacement for Windows. Sorry I misunderstood, it is desktop environment, therefore my post is irrelevant.

 

Puppy Linux is KDE.

 

No, it's JWM or Openbox by default.

 

XFCE because it's light and stable and works great on my older hardware.

 

I use Unity.
I think it offers an efficient and usuable experience out of the box.

With tweaking XFCE is also sufficient for my needs.

 

Using Unity now, also enjoy Xfce as well as Cinnamon...

 

I installed Ubuntu 12.04 LTS dual booting with Windows 7.

 

Glad to see that Im not the only one who likes Unity

 

my favorite is still gnome 2.32 desktop environment or 2.28 of redhat 6 clones but after that i like cinnamon very much

i give unity/xfce same score

then kde because i am not kde fan

but last which i dislike the most is gnome 3.x.x

it make me feel like changing a hot wife stable happy relationship for some weirdo chic

 

Found xfce and never gone back.

Also, long time user of Mint, after some time with Mandriva, PCLinuxOS, and Puppy.

KDE – Unity – and now that I can use Cinnamon – that too!
(In no particular order of preference)

 

KDE - Be Free!
Platform Version 4.11.3

 

Linux is not my first OS, anyway I love Gnome and KDE ! I can't understand which I like better.

 

Xfce with gnome-do.

 

Almost said Android.

 

Just switched from Unity to MATE. I have to say I miss that extra real estate. I wish there was a nice way to force program options into the tray like Unity does it.
