Definitely 'Godiva'. Sounds better. Much, much better. 'Godgyfu' sounds Japanese. Not that I have anything against the Japanese or anything. It's just that, they're not known for their chocolate-making skills. Surprisingly, it's something they still haven't found a way to take apart and copy.
'Godgyfu' also makes me think of 'Podgyfu'. Not a good memory if you're trying to sell chocolates. Also, 'Godgyfu' is not easy to pronounce. End of 'Godgyfu' story.
'Godiva' wins this one hands down. It makes the sayer open up and say 'aa', always a good thing when you're in the vaguely sexual space of chocolates. 'Godiva' also sounds Swiss, French, Belgian and all those wonderful European places that make the most heavenly chocolate. Importantly, 'Godiva' takes the mouth through the 'o', 'i' and 'a' sounds and when a name makes the sayer utter these most basic, most expressive 'intonations' in a product the reminds people of sex, know this, you're onto a good thing. Unlike in the case of 'Godgyfu'.
