After power of x, i do agree, but is not the same Apocalypse, maybe the fall happen in different order, he "betray" them but Moira revealing herself makes him back on track.
But i blame Hickman for this, he show me the main event in the begining, post-humanity, so now, i dont care about this new villains, they dont feel big for me. The big thing is Orchis and the Phalanx.
Thats why i revert back to the mutant villains, they are way more cooler that the human ones, making Magneto a hero was controversial at the time and we know that many writers dislike that, losing another great villain without a worthy replacement can be hard.
