Vegemite vs Marmite

I am a vegemite eater.... yep I have said it, I don't like marmite, I will eat it if I have too but would rather not touch it.

But what I really wonder is why this polarises people.... why is it one or the other, does it have to be one or the other? I don't know of any other spread that has this one vs the other going on or does it exist and I just haven't heard about it....

Maybe its just a kiwi or aussie thing, Ben doesn't like either of them, he prefers Nutella, so it might just be an antipodean thing....

Either way I am intrigued by the whole thing and wonder what others think.
