I agree and disagree with both of you. There are real, tangible advantages and disadvantages to both.
My approach is to embrace both at the same time, by almost always coming into the office, but arriving before 0700. The first half of my day is super focused, uninterrupted work, and the second half is relatively unfocused, talk to people and be talked to at random times kind of work. I leave around 4pm.
I've had no substantial problems going home so 'early' among the eight or so orgs I've worked at in the past couple of decades.
