Pretty much - the rocket is smaller & you can usually also get more thrust, while loosing some efficiency. There are were more rockets like this (kerolox for first stage & hydrolox for upper stage), like for example Atlas 5. Other rockets used kerolox boosters, such as for example Energia & IIRc some of the new Chinese rockets.
