Jason, if I were to do a detailed statistical analysis of the distribution curve for each architect, you'd find that Strantz leads the field in diversity of judgments on him. In other words, he tends to spread the field more than any other architect. Pete Dye is probably second. Fazio is at the opposite end of the spectrum, with a very tight distribution pattern of votes.
What I think I see with Strantz, and it's an impression that I'm not really sure I can verify given our limited information retreival on this, is that Strantz garners a good mix of 6s-7s-8s-9s but also more 4's and 5s than a lot of other big name, creative designers. Dye, tends simply to polarize, with the votes being not so much evenly distributed as more split. Fazio clusters.
In other words, Strantz's creativity is stirring and impressive, but also a bit jarring. For everyone who thinks Caledonia's little par-3 9th is a great contrast hole, there are raters who think it hokey and shoe-horned in as an afterthought. The same goes for some of his green complexes -- this as far as I can tell from a gleening of the data, as well as conversations with raters.
Personally, I find some of his work absolutely stunning (Caledonia, Monterey Peninsula-Shore, and some of it absurd (Stonehouse). And some of it all at once (Tobacco Road). But I also love playing his courses for the strong emotions they elicit.
