You can also make gnome look like windows or kde look like Mac OSX. There really isn’t a limit to customization for Linux. F.e. I use kde but have it look like/close to osx, because I prefer how kde manages multiple displays. I do like gnome, but I cannot stand it’s stubbornes (or maybe my stubbornes?) with multi screen setups. There’s many ways and you can choose the one you like most, that’s the beauty of Linux :).
