If you hired Larry Haun and his brother to frame a new house, they'd have it done in a day or two with nothing but nails, a hammer, a SkilSaw, a framing square, a chalk line and some chalk. If you hired some random contractor, it'd probably take six guys a month, go way over budget, the job would be a mess, and they'd have used 15 different tools.
Larry is better not because his tools are better, or because one tool emphasizes how to use it the right way. Larry just knows his tools and knows how to do the job well with them. And that isn't to say that using any tool at all is fine; an unsharpened rip saw will take a hell of a lot longer to use than Larry's SkilSaw. But the outcome of the project still depends way more on Larry's skill than his SkilSaw.
