I do think it kinda cheapens the world building.
"Garlemald is the most civilization ever!"
"Allag was the most advanced civilization ever!"
"The Ancients/Omicrons were the most civilization ever!"

I think on some cases- like the Ancients or the Omicrons- it's justified and flows well with the story/lore. But I felt Alexandria being compared to Allag (sometimes in terms of relative superiority) felt a bit tired.
