I want to ask politely for an in-depth explanation of how these two apparently similar things A and B are different when closely looked at.

Eg: "In which way A and B are different from each other?"

  • “I know A and B are very similar, but I was wondering if you could explain some of the details on how they differ.”

  • Note OP asks for “polite”. The questions proposed in comments and answers certainly get the intention across but they do Not have any added elements of politeness.

What are the subtle differences between A and B?
