Penacony:
-High fantasy
-World story doesn't overstay its welcome
Main characters like aventurine and sunday are properly developed in the story
-Amazing godlike OST that you can instantly recognize
-Almost every area is absolutely breath taking, even 2.3's filler ass airship
-Every character that came out of penacony had GREAT designs
Amphoreus:
-Generic greek slop setting
-World story overstayed its welcome two patches in
-Every character in its story is half assed and doesn't have any actual character nuance. Tribbie and cipher are the only ones not completely dogshit
-Completely forgettable OST, there's maybe a handful of tracks anyone remembers
-Every area looks the same from the last one. Aquilla area is probably the only zone that looks very distinct
- Designs all over the place, characters outright look like they're AI generated (hysilen) or they're lazy expies (Hyacine, Cerydra)

Just admit it. Penacony > Amslopeus.
