I use the CLI, too, but I enjoy watchinng people use the desktop apps. It seems like the desktop apps may be a little bit better suited for human-in-the-loop work. If you're already switching back and forth between a mouse, having an IDE running may make more sense.

The best feeling has to be in the CLI, in my oppinion. A low-stakes project where you can let ultracode runaway from you in the CLI is the most fun.
