I generally dig the monster figures in the official D&D Minis line, at least the ones that appear in the Monster Manual. But between the figures for critters appearing in books I don't own and some of the more outre personality minis, I'm not 100% satisfied with the line. So I supplement my figures with some Heroscape sets and paper figures (most notably S. John Ross's Sparks and Steve Jackson's Cardboard Heroes).
In terms of design my tastes align less with the dungeonpunk of modern D&D and more with things like Reaper's Dark Heaven line. Admittedly, the Reaper figures evoke more Elmore and Warhammer than I generally prefer, but since no one is rushing to produce an Erol Otus inspired miniatures line where else can I turn? Still, the question posed in the title of this post remains: Do I like Reaper's minis because they're good, or because I cling to a outmoded vision of D&D? I think the answer is a little from column A and a little from column B.
