I don't get why you compared these two, they're from two completely different genres. Personally I'm not a fan of either but I guess I'd have to choose Iron Maiden simply cause I don't hate them as much as I hate Madonna's music.
You should know my answer. Eddie alone would make Maiden win. While both are very juicy and sweet fruits, apples are usually sweeter, but can be tart or even sour, and have edible skin, and technically even cores (but ew). Oranges are more sour tangy, acidic and very citrus-y but still very sweet, with a rougher outer membrane and a softer inner, pulpy texture; the peel is thick, bland, and foamy, with a bitter oil, so it is usually removed.
depends on what you're comparing. i'd be infinitely more likely to have sex with 1980s madonna than 1980s iron maiden, for example. current versions of each, it would be about the same either way.
Like a Virgin? Or, if we're talking about I'minmyunderwear, The Number of the Beast. Really, the only thing Madonna has going for her here is that Weird Al's never done an Iron Maiden parody.
