I'd hafta go with the alien, because it's always a great thing to have the ability to do the higher extremes, even if you don't always use them. Think of it like a phone. If, you had a phone that was fully waterproof, even if you just left it in a pool for twelve hours, you wouldn't be worried about splashing it a little, or using it with wet fingers. This is especially true when you think about burning coils, that is such a pain in the neck, you want to avoid it at all costs.
