I agree. I'm just saying this isn't an "engineer" versus "designer" issue. Engineers have just as many "irrational" opinions as designers. Emacs vs. Vim, Ruby vs. Python, or whatever. And those things are quantifiable to some extent. Take a random sample of engineers, give them identical tasks to complete, and vary the editor.
