I personally find that sculpting pushes the topology around to places where you don't want it to go, whereas with modelling you have more control, which in turn makes it look more crisp. Saves time because then you don't have to retopologize. Unless you're doing something extremely detailed or are good at sculpting in 3D, that is. 
This video helped me learn the basics of modelling, might be useful to you as well.

I only say this because retopo can burn you out quickly.
