Yeaaa- no. Those are all terrible examples. You can't point at fights with some of the most powerful villains in the series and then claim that those captains were "weak" for having trouble with them.

Baraggan was the worst possible opponent for Sui-Feng. He had what was easily one of the most overly powerful abilities in the entire series, and it was only by pure circumstance that Hachi happened to be able to exploit his weakness. Hitsugaya literally held back against Harribel most of the time since he didn't want to accidentally kill anyone on accident - he only resorted to Hyoten Hyakkaso (an upgraded version of an ability he could barely control in the SS arc) when it became clear that they were evenly matched. And seeing as most of the Sternritter we have seen are horrendously overpowered in general, using BG9 as an example is pointless, especially since Sui-Feng's fight with him just started.
