Looking to book return flights from Zurich to Japan (doesn't matter which main airport, would rather avoid Narita though) and after endless hours, the best flights I can find are;

Cathay Premium Economy


JAL Economy


Normally PE would be a no-brainer against Economy and a 30% premium would be reasonable but with JAL's amazing reputation and Economy being 2-4-2 and Seat Pitch and Width being similar to PE on other airlines I really am unsure.
Help!
