From my understanding, the primary LASTING difference is bone size. If someone goes through puberty as a boy, they're likely going to have longer bones... so taller with longer limbs, on average.

But the density of those bones would change with hormone therapy. So would body fat composition, muscle size and strength... negating the advantage of going through puberty as a male for many sports.
