The one who emphasises quantity is the programmer reading the output. A craftsman shouldn't be blaming his tools. That said, I've always found the percentage readings useless prefer to run my testcases directly rather than under harness.
chromatic and Ovid have recently been better men than you or I and got down to actually do something about this in the form of better test suite output. I particularly enjoy chromatic's supression of the output of passing tests. That would seem to be what you're after, as well.
