The shell from Plan9, rc, is simply the one I am most comfortable writing in. It has very straight-forward syntax. And while the language is very powerful, it is small enough that I can remember most of the quirks. But I do not think it is objectively better than other scripting languages. It is the same with mk (the Plan9 redesigned make). They took a few lessons from problems they had discovered in make and improved them. And made it simpler in the process.
