I agree with Old Dad, here-- at least until mid-adolescence, the relative importance of the two things may ultimately be about at parity.

Even though it may not seem that way now, having really excellent social skills (and a way to exercise them regularly) is perhaps even MORE essential to kids who are non-normative.

I say this as someone whose socially-adroit introvert has always been home-educated; you have to work QUITE hard to make sure that such children get very regular opportunities to socialize within a structured activity. Because that is what schooling provides in such abundance, and it's the foundation for working with others in higher education, in the workplace, etc.
