I've shown Sacrifice to people who became Wonder Woman fans after reading it.
How could it not showcase Wonder Woman's powers in interesting ways when she used her tiara to slice Superman's throat? How does it not say something about her personality when she asked the right question and was resolute enough to do what had to be done based on the answer, despite the consequences?
It's a beloved story and in it she comes off looking better than Superman or Batman. That's what makes it good.
