I struggle to understand where people's estimation of Proxima comes from. What impressive feats does Proxima have ? Clearly she's strong, but other than momentarily overpowering Black Widow, she hasn't really done anything impressive - I dont think she's strong enough to take out a giant wasp, she hasn't shown any strength feats that suggest this.
Given the array of weapons Wasp has ( blasters, the ability to grow/ shrink herself and other objects , plus her own fighting skills ) I honestly can't see her losing this one.
As for strategy or adaptabiiity well I can't see that either, based on her appearances in the films - Black Widow is a very different story.
