Most of the issues with Komamura from the fandom (at least in my opinion) come from the Worf effect. Sure he's got a big, badass shikai/bankai that should theoretically be able to just completely decimate anything in its way, but pretty much every time it's used, he gets beaten to showcase how strong the other guy is. His one "victory" (not counting anime filler) wasn't even against an Espada, but a Fraccion. His climactic battle with Tousen? He gets one-shotted and Shuhei steals his thunder. His track record isn't exactly spotless, so I really and truly hope we don't see him getting destroyed by Bambietta (which is what I unfortunately believe will happen, given Kubo's love of seesawing who's stronger in any given fight).

The same applies to Shinji really, though he at least got to show off that he's stronger than Grimmjow. His failure versus Aizen makes sense, given his opponent. I think a large portion of his issues in the fight from Bambietta come from his lack of ability to just use a cero/hado/any attack at all. He just sits there explaining his ability and gets slammed for it.
