shrug - Like I said, it's a matter of aesthetics and usability for me. I've never met a Linux UI I liked (except for XFCE a long time ago), and I go out of my way not to use non-native apps on OSX. It's all about personal preference. I also dabble in design and UI/UX, and have for some time, maybe that's why.
ps. easy_install is bad for you, use pip! http://www.pip-installer.org/en/latest/index.html
