In most cases, the very best hitters have the qualities needed.
So pitch recognition, patience, discipline, educated guessing, self knowledge, all go hand in hand with aggressiveness and physical hitting ability. Most of the best hitters combine patience and aggressivness. That is exactly what Barry Bonds learned to do. I know some claim it was all due to steroids, and maybe that contributed a lot. But he also learned how to combine patience without giving up any aggressiveness.
There is no question that walks help win or lose games. Just ask any pitching coach. Those walks mean more at every level. But you can't reach the higher levels unless you show that you can hit. And you can't walk if the pitcher throws strikes. And you can't hit very well if your swinging at pitches outside the strike zone. The best pitchers love to face the hitters that chase.
