My favorite issue is 79 by Peter David, part of the series final arc from 75 to 80.
This is the Supergirl from Death of Superman, matrix, with human Linda Danvers integrated into her.
At this point Linda is the only personality.
In issue 75 the real Kara shows up.
In issue 78, Linda takes Kara’s place as she goes to the Earth that she was destined to die, that of pre crisis.
In issue 79, both Kara and Linda appear.
There is one page where Linda describes her three years there
Heroes enjoy being heroes
Villians have elsborate plots but do not kill
In this page, she rides Comet and has picnic with Superman, Streaky and Krypto.
And then it gets better.
She is not the cousin of Superman and he knows it, and they marry.
Superman says lois only wants to learn his true identity.
There is a daughter.
Meanwhile, on other earth
Mere hours have gone
Mom of Linda having baby
Kara in trouble.
Hal Jordan Spectre apears to Linda
On to final issue 80
All done in 23 pages
Tom King and Bendis would have needed 50 issues.
