Well, Akira is physically stronger. In terms of speed, Medaka is probably faster. However, Kongo has fought characters that are much faster than him before, like Iai Banchou and Machine Banchou, and came out on top.
I'm not sure, what else can you tell me about Medaka; I'm not exactly an expert on her.
I thought that only works with abnormal abilities. She could also learn skills instantly via that method if I remember correctly, but I'm not sure if she could do the same with Kongou's strength since it seems to just be a natural thing that runs in his family.
