There are roll crimps, tapered crimps and the so called factory crimp. The first two are accomplished by differing profiles of the constrictions of the crimping dies. The "factory" crimp is accomplished by a collet. Your crimp type is usually dictated by the nature of your bullet and your application. I use a "factory" crimp collet only when loading jacketed rifle bullets with a cannelure.
