I agree. I have a H10-13.4, that I've used for about 5 years now, and I love it. I've never had a problem with it. On days when I'm actually busy, I can wear it comfortably on back-to-back flights all day without it making my head hurt. I'm not a big fan of ANR (or ENC, whatever you prefer to call it), so I like the simplicity of the 13.4, but I've heard the others are good as well.
