I benefitted massively both from skipping a grade, and from skipping ahead in math, science, german and french. I was obscenely bored, and wouldn’t have learned a thing (except for how to goof off more effectively) and would have distracted my fellow students to boot. You develop the soft skills of sitting in class whether or not the other kids sitting there with you are a year or two older than you. I don’t think ego enters into it at all.
