I think Ayn Rand is writing to an audience who already fundamentally agrees with her ideas. A lot of her writing strikes me as clarification of her philosophy, rather than a justification of it. I didn't get that same sense from Pirsig, but while the ideas he presented were interesting, I didn't feel I was getting a novel perspective on them.
