Deciding on the "correct" cocktail shaker is a matter of taste and practicality, and you may become comfortable with any model you choose. If your interest is clean ease of shaking, a three-piece shaker may be your solution. For working bartenders who might be looking for speed, a two piece system of capping a smaller tin or mixing glass is common, as is preferring instead a single tin for mixing and a cocktail strainer to separate the ice. Two piece shakers can come as a set, and oftentimes having a matching look is a large consideration. If you're looking for a bit of flair and no slip grip, you may want to consider the vinyl-coated shaker. Choosing metal or plastic is a factor when purchasing limits and showmanship for both pros and home bar enthusiasts are important factors.
