It makes negotiating situations where you need power on tap right away, not 2 gears away, that much less stressful.

Why do you need mud tyres?
Why do you need lifted suspension?
Why do you need diff locks?
Why do you need a bullbar?
Hardly any of us NEED these things, but we get them anyway because it makes our vehicles more capable, and generally more enjoyable to use in whatever their intended purpose is.
