The fact she was captured so quickly implies to me that Yhwach didn't intend to take any chances and we have no idea how many Quincy she took down before she was beaten.
Extremely doubt it was Harribel.

Firstly, she wasn't stronger than Bankai-weilding captains. She fighting evenly (arguably losing) to the weakest Captain by himself, before his post-Aizen training. She's the strongest alive mostly because Starrk and Barragan are both dead, and since it seems to be generally accepted that the person that showed up and finished Opie was Grimjow, she may not even be even the strongest Arrancar anymore.
