Dear teachers,
I asked a question of 'measure against' and 'measure with'. And the following is what Cas explained. I thought I understood it but I'd like to make sure I am right. I have waited for Cas for four hours but she hasn't replied yet. I guess she is too busy to help me. Since this question is urgent and I am not sure whether Cas will be free today could you please kindly help me?
The following is the sentence:
Heroes and heroines are men and women distinguished by uncommon courage, achievements, and self-sacrifice made most often for the benefit of others---they are people ________ whom we meansure others.
The following is Cas' explanation;
with whom expresses a comparison based on similarity, whereas
against whom doesn't. For example, A against B (one is better than the other) versus A with B (they might be equal). Does that help?

My quesiton are:
No.1 A against B: one (A) is better than the other ( B). Is that right?
No.2 Then in the cited sentence it should mean: Others are better than 'they'. That is 'Heroes and heroines'. What puzzled me is that it doesn't seem logic.
If I am wrong could you please explain how I can decide whether 'A is better than B' or 'B is better than A'?
Looking forward to hearing from you.
Thank you in advance.
