Yeah, as for development I'd say Linux (or any Unix-like) is more suited for that, especially when you have really great shell, development utilities and awesome package managers, and the overall system design is good for that. Also some stuff is just faster to do in command line, I could never see myself using git graphically for example, as doing so only gives me more headaches. But for most stuff I prefer GUI, because GUI's tend to have common design choices, and you can generally figure it out in few minutes, while for CLI utilities anything goes, some have built-in interactive prompts, some incompatible syntax, there's sometimes steep learning curve, and list goes on.
