There clearly is not one-size-fits-all. During my career I had quite a few managers. I recall a lady which essentially just ordered us pizza (I'm not making this up). She wasn't the worst manager I had (but yes, hardly worth the money). A few times I worked for fellows who wore two hats, engineer and manager (but presumably got only one salary). I enjoyed that for the most part, as there was little friction within the team, but observed that it wore out said manager due to workload and friction with higher-ups. I've been in a team which was large enough, we couldn't find a room for all to be seated. That was a disaster (also unrelatedly due to the Peter principle). I've been in a two-man "team" with the owner of a start-up. That was quite productive, but probably not very cost-effective.
