Time is money, so I set up my main PC for maximum productivity.
Everything I use the most is no more than a click away, and I have a batch of fave useful CLI and keyboard shortcuts and commands. Life is too short to wade through inefficient GUIs. I like all Linux graphical environments, and the one I keep coming back to the most is KDE. I loved it when it was pixely and not very pretty and had tons of customizability, and now it is sleek and gorgeous and has tons of customizability.
