In regards to focus and typing speed, laptops seem to do it best for me. My laptop is usually in sleep, and my desktop off, so it’s much faster to bring it from sleep and do what I need to do. A laptop, too, was my first computer, so I feel fairly comfortable with the experience unless I really need a mouse. Desktops are insanely comfortable, though, and I guess primarily that’s what I’d use, but thankfully I can do about equal things on both outside of gaming, so it’s mainly about how I’m feeling at the time.
