I think Batgirl’s fighting skills have gone backwards, frankly, after I left the book. I’m not saying it’s a bad thing, but they definitely made her younger and less experienced. So I feel like Batwoman still has the edge, at least from what I have read lately.
My feeling was that an experienced Batgirl OR Oracle would have taken Kate down. But she’s being presented as pretty inexperienced, currently.
Again, not a value judgment, I like inexperienced characters at the start of their journey. But it feels like Kate is ahead of the current version of Batgirl as a fighter and possibly even as a strategist.
