Having read biographies on both fighter and bomber pilots then I would say that the fighter pilot needed to be very independant. once the battle started he had to look out for himself and maybe his Wingman, but that was it. he was alone, he needed to be a capable flyer, instinctive, very quick thinking, and aggresive.
In opposition the bomber pilot had to be steady, sure, a good flyer, always thinking of his crew before himself, nerves of steel and icy cold. And most importantly a team leader.
The most successful fighter pilots began to develop the team ethic of the bomber pilots in order to lead the wings, liek Bader or Johnson, but in the end the Fighter pilot, in my opinion, needed to be a maverick whilst the bomber pilot needed to be dependable.
