I'd agree it very much depends on the individuals. I have worked with people all across the spectrum. My advisor was absolutely in the "good" camp - we'd openly describe call academia the "world's biggest hidden pyramid scheme". He led a small, tightly knit group, and the group followed the two pizzas rule.

I've also dealt with people who tried to come across like this, but were the absolute opposite - they'd grown a pretty large research group to get their chair, but had a reputation of over-promising and under delivering. They'd promise things without the technical knowledge to understand what they were saying they'd do, then causing morale problems among their team when people found out what had been promised. They absolutely didn't follow the two pizzas rule - you could barely find their whole group, let alone fit them in a room. This prof would try to give the impression they wanted others to grow and succeed, but ultimately it was all about them, and preserving their carefully crafted hierarchy. They didn't like to hear "no", and couldn't bear the thought that they were over stretched and not delivering, so everyone would tell them things were fine, as they under-delivered, exacerbating the situation...
