My DD developed spoken language faster than DS. Her FSIQ is lower than his and I think that's accurate. Language is a huge area of strength for her, though. DS read earlier than DD. On the other hand, I was a late talker--didn't talk until I was three. My IQ is in the HG range. So personal experience makes me skeptical, too.
