You mean disadvantage? The main disadvantage to the host is that the organism absorbs and uses nutrients which otherwise would go to the host. Sometimes the worm could also obstruct the intestines.
But maybe you are actually asking about the prevalence, in which case I don’t know. This would be the same as asking "How do rates of human infection compare among beef, pork, fish, and dwarf tapeworms?" or more simply "Which tapeworms infect humans more?"
