People always forget the keyboard-only option when asking questions like these. :P I find it cumbersome to try to use mouse, it's a lot faster for me to do everything from the keyboard. Don't even have a controller for PC, and I'm rather certain I'd find it a lot more cumbersome than even the kb+mouse system, a lot more switching there since you can't type from the controller. So yeah, if you haven't tried keyboard-only control system you might want to give it a go, see if it fits you.
