I believe most objections to GUIs come from people who've never experienced good mouse control. If you're not using a high-end gaming mouse and a high refresh rate monitor, with sensitivity/acceleration curve selected with careful thought, on a mouse pad that suits your settings, you probably have bad mouse control.
Watch some videos of top-ranking aim trainer players so see how high the human skill ceiling is for mouse control, and look at the hardware they're using.
