@Switch Blayde"Futanari" sounds cooler since it's Japanese. :)
On a more serious note, I've seen people argue that there is a difference.

A Futa would have a cock and pussy but no ovaries. A hermaphrodite would have a dick balls puss and ovaries.
The wiki article on Futanari disagrees with that assessment.

Beyond Japan, the term has come to be used to describe a commonly pornographic genre of eroge, manga, and anime, which includes characters that show primary sexual characteristics from both females and males.[1] In today's language, it refers almost exclusively to characters who have a gynomorph-female or overall feminine body, but have both female and male primary genitalia (although a scrotum is not always present, while breasts, a penis, and a vulva are). In rare cases of otokofutanari, instead of a woman, it's a andromorphic-male or overall masculine body, with a penis, a vagina, and muscles instead of breasts. In gyaku-futanari ("reverse"-futanari), instead of replacing a woman's vagina with a penis, replace a man's penis with a vagina (this never counts as a hermaphrodite; in English, analogous term for it is "cuntboy"). The term is also often abbreviated as futa(s), which is also used as a generalized term for the works themselves.[2]
