It's deceptive to compare the two since the shuttle really is good almost exclusively for ISS missions, Hubble repair, etc (unique Canadarm capability) while F9 is the cheapest there is for Satellite launches at $2,720/kg. It isn't so great to require a crew for a satellite launch. The shuttle can only stay docked to the ISS for about 14 days while crew dragon can stay for over 180 days.
