My thoughts on tools today are kinda fuzzy. To some extent, I think the most important aspect is results.
I agree, though I see results in more abstract terms than you. Not so much "how fluid and flexible is the line?" but "what is the effect on your audience, and how close is that to the effect you wanted to achieve?"
Scroll down to "The Philosophy Issue." There are guys there who have real trouble with the idea that apparently subpar beans (static, marker-like lines) can yield superior espresso (aesthetically pleasing visual art).
