In my opinion Squall and Cloud are very much the same. They both are sarcastic and emotionless at first but throughout the game's they both develop a sense of love and passion for the people and world around them, With this motive anyone can win. The passion is the will to do what you think is right and fight for who you care about.. But I'd say Cloud has alot more passion as he's lost alot more than just the world around him.. he lost a close friend too giving him the power to fight his enemies for that friend's benefit. Squall on the other hand is only protecting his friends and the world. His emotions are like Clouds and he develops these after he meets Rinoa. Even though there were times where Squall almost lost Rinoa.. he did not lose her. Therefore his passion to fight was alot less powerful than Cloud's.. So putting the two together with these motives. If each was an enemy to each other, I'd have to say Cloud. Due to the passion he has for fighting and protecting others.
