1:1® Actuation is superior by design. Every unit of cable you pull moves the derailleur the same amount. Actuation stays precise and fluid slogging through mud, bouncing off rocks, rutting through roots wherever you find yourself, whatever conditions you're in. It's dependable. Tolerant. Easiest to set up. Easiest to adjust.
