The trouble with chair recommendations is that the best chair for me isn't the best chair for you. If you are able, going to a warehouse or store of some kind where you can try the chairs out will make all the difference.
To answer your q directly: I have tried Herman Millers in the past but they just didn't do it for me, too stuffy and I dislike the arms. I went for a Humanscale Diffrient World instead, it is all mesh which is perfect for summer. I'm able to lead a sedentary lifestye in it without discomfort.
The benefit of chair recommendations is that you've likely spent longer timespans in your chair than I can reasonably spend in a store. In my experience, recommendations tend to yield better comfort long term than my own opinion in a store. But maybe others are better able to extrapolate. Honestly I've never found an office chair that I'd call comfortable.
