Ablarc: I find myself in strong agreement with this compilation, and I appreciate the inclusion of some of my additions. I think that whenever putting together a list such as this, the easiest tasks are selecting the upper echelons and the bottom-feeders. And, while it's not practical to do a strict black-and-white, good-and-bad list, I find those middle gray areas to be most troublesome. In this case, I don't have many quips. I would, however, consider moving Herzog de Mueron up one spot, and shifting Graves down one (this based mostly on the quality of their most recent work). Maki's a tough one because of his lack of exposure outside Japan; I think his new WTC tower will solidify his position in either this group or the one above. Finally, I'd like to add Kohn Pederson Fox to the mix. While they may ostensibly fit well in group 4, I think they've proven themselves to be a cut above the other big corporate firms (including SOM, as whole).
Good work, and I hope to see a broad response from the forum.
