Also, the coil in Handbag zippers is slightly wider than the coil in dress zippers - Handbag zippers coil is around 3/16" (4.5 mm) wide vs. 1/8" (3 mm) coil in dress zippers
In General, I would say that Handbag zippers are more suited for heavier use, and the longer pull looks better and is more practical for purses. Dress zippers are more concealed and are more suitable for garments and small pouches.
Here are a couple more photos of dress and Handbag zippers that are available for purchase:
