Bulbed keels are used on "normal" draft boats, wing keels are used in swallow draft boat as a way to partially compensate the difference in draft. The compensation is some but not much. The draft is very important to a sailboat, not only to make it lighter ( a wing keel has to be heavier to compensate the RM) but to better the upwind performance.

If you want to have an idea of the difference in performance you can go to a PHRF list and compare the same boat with wing keel and deep draft and you will see that there are a very considerable difference.
