Please do not think as a fanboy, leave everything aside that might influence your opinion, such as: suspension of disbelief or "come on, it's a comic". The question is comic-independent. It's not about what sounds cool or what would be more practical, faster or easier. It's just about what sounds most believable or convincing.
