As Marty Gillens argues in his book Affluence and Influence (http://press.princeton.edu/titles/9836.html http://press.princeton.edu/titles/9836.html), on almost every issue there is a sub group within those who feel a particular way on an issue that is highly informed about that issue and a subgroup that is less informed. 1p1v gives both groups equal weight while QV gives much more weight to the informed. This is much fairer, because the uniformed group will typically be easily swayed by advertising and manipulation to vote the other way, making groups with more uniformed people easily undermined even if there are some members that are informed and who could speak for this group's interests. This is a major problem in American politics: the poor often favor less redistribution than the rich do (again see Gillens)! So I actually think QV would improve the situation precisely along the dimensions you are highlighting.
