It was a break from the regular writer/artist team as these 3 issues were written by Gerry Conway and drawn by Jose Luis Garcia-Lopez.
Supergirl basically gaslights Superman by trying to convince him that Krypton never existed and that even the bottle city of Kandor is just a model with no real people inside. She smashes Kandor to the ground to prove it to him. I won't spoil it any further.
In a sense, the story is like something that would have appeared during the Mort Weisinger run (even though this was when Julie Schwartz was editing the book) when Superman's friends were being dickish to him or he to them and it wasn't until the last page that it was revealed that it was all done for a very good reason.
What made this 3-parter stand out is that Gerry wrote Superman Marvel-style. That is, he begins the story by angrily destroying something -- a nuclear power plant, I think. When Supergirl starts to play with his mind, he gets really freaked out and becomes really unhinged. Garcia-Lopez's art really sells it. Superman looks like he could snap at any moment and go on a rampage. I didn't like it too much when I first read it as a kid because Superman is acting so out of character and not like his usual kid-friendly self, but as I got older, I did appreciate it more. It's kind of a fun story and definitely a dramatic change of pace. Conway really married the Marvel melodrama style with DC's gimmick-plot oriented stories here.
Another suggestion is a 4-part story that soon followed the Conway one. I believe it was written by Martin Pasko and it was a take on the "Legionnaires' Disease" that was a real-life story at the time. It featured Amalak as the main villain. It appeared in issues 311-314.
