Some designs are better than others, yes, but there comes a point where it's a sliding scale and you must compromise one attribute to gain another. I went the stepped header route, though they are still waiting to be installed.
I definitely agree with many of the things you mentioned. I'll shoot you a PM back so we can further discuss it there. I don't want to detract too much from Diokaef's great thread.
