Well, he looked near overpowering on Grimm when he went Hollow, but when Inoue made her little scared face and you saw Ichigo's reaction, notice how he suddenly started losing. Spirit and support do count for a lot, in Anime and real life.

Take, for example, in Samurai X, in Kenshin's fight against Tomoe's not yet deceased fiance. He scored a hit on Kenshin due to that spirit, while we've seen Kenshin go against a fair sized platoon of experienced warriors and come out with no injury.
