This is almost like picking your favorite gun. So many good ones to try and choose the one you like best. Of course a lot depends on your use such as hunting , target, defense, or just plinking. Of them all I think I would pick the .38 special. It can be used for just about everything you could use a handgun round for in the United States. It can be loaded down for target use and plinking or powered up for hunting. Not the best for everything, but a good compromise, including price.
