I'd say decision making and leadership are more important than beautiful passing ability. Your categories seem to overlap a little.
Wins are ALWAYS more important than stats.
IMHO, one of the best passers recently was that moron that played for the Colts, Falcons and Raiders. He threw perfect, laser-like accurate passes but he totally lacked leadership skills, and his teams won plenty of games but when it REALLY mattered they always faltered.
Montana, Brady even Plunkett are more my type of QB. Smart, gritty and TOUGH.
