I don't think they sell Mars bars here? I don't think I have seen one, but I don't hang out in the candy aisle though...anyway it sounds like a Milky Way which is fine but feels empty without the nuts - all this to say, Snickers
I don't like either. I used to like Snickers a long time ago, but now things like Snickers, Reese's peanut butter cups, etc. just taste like salty concoctions of chemicals to me.
