Unless you're writing ruby on rails on a 13" macbook, you'll run into Gnome's limitations when working.
Gnome is in many ways so focused that it makes a lot of productivity use impossible. You always have to open the menu to launch software, you've got no system tray, and worst of all, Gnome apps are so simplified that you constantly run into the limitations when using it productively.
When working with dozens of windows open at the same time across multiple monitors, I'm a fan of KDE. And KDE apps tend to also have all the extra features I need to handle weird situations, files, and edge cases.
Why'd you have to use TC? KDEs dolphin can do all that natively.
Personally, configuring KDE was much simpler and more robust compared to the dozen addons I needed for Gnome, which also broke every now and then after updates.
