I still like the look and feel of GNOME a lot so I spent a little time putting it together that way. I want a simple desktop with small elements to maximize real estate for windows. I also use the small taskbar on my work computer for the same reason. But with my work computer, I do show window titles because I usually have at least 5 workbooks open at once so it's nice to see which is which when I need to switch between them.
I love KDE's application launcher. It feels very Windows XP with the way it sorts things. It just makes complete sense.
Century Gothic may not be the most readable font in the world, but I think it has an old school charm to it.
I stopped using gnome after they removed the ability to edit the menu without going through a bunch of hoops. Their idea of removing complexity involved removing choice and customization. KDE has had superior multi monitor support for a long time.
And as a multi-monitor user, I'm finding that part to be true. I've got my panels set up on each of my monitors exactly the way I want. Plus, controlling the wallpaper independently on each monitor as a built-in feature is dope.
