In Endgame, they went from 50% (3 and 1/2 billion people on Earth) to 100% (7 billion people on Earth) and then Steve Rogers went back in time and permanently erased Peggy Carter's children from history. Not to mention the millions (who might not have been dusted before) who would die from the famine and starvation caused by the Avengers suddenly increasing the population of Earth by 3 and 1/2 billion overnight. No such famine and starvation would've occurred in Crisis on Infinite Earths.
You seem to be under the misconception that when they restarted the Big Bang, they got to choose which universes would be re-created and which universes wouldn't. They had NO choice. All they could do was restart the Big Bang! Then it would be up to science to determine how many universes would be created from the Big Bang.
Heck, after the universes were started, Supergirl and Flash each thought they were on their own Earth and didn't even know that their two Earths had merged. So that proves they didn't combine the universes or rewrite history. The multiverses had been destroyed by the Anti-Monitor. All they did was restart the Big Bang. Then it was science that determined how many universes would be created from the Big Bang.
In Endgame, Steve Rogers went back in time and made the selfish choice to permanently erase Peggy Carter's children from history forever. Unlike Crisis on Infinite Earths, where the heroes had no control over how many universes would be created from the Big Bang, Steve Rogers did have control over whether or not Peggy Carter's children would be permanently erased from history. And Steve Rogers made the selfish choice to permanently erase Peggy Carter's children from history.
