The only fights that Sui-Feng has ever "lost" throughout the entire series have been against Yoruichi, Baraggan, and Aizen. I just named her former master, who has every reason to be stronger than her, and two of the most overly powerful villains in all of Bleach. And Sui-Feng is weak for that?

The only opponent that Hitsugaya has ever outright lost to has been Aizen. Overly reliant on his sword? It's his Zanpakuto. Why shouldn't he be reliant on it? It's literally a part of his character. Harribel was at just as much of a disadvantage against him as he was against her - in fact, as I've already stated, he was literally holding back up until the very end of his fight.

I won't bother arguing with your statement of their being "boring," but your arguments regarding their strength are ridiculously biased, not to mention speculative.
