I'll just list their advantages:

Cipher: He actually FOUGHT at B7R. He knows the terrain better than the others.

Blaze: He contributed to the defeat of 2 of the most dangerous Belkan Aggressor Squadrons in history.

Garuda: IDK, never finished AC6 (Disk FUBARs past blowing up Aigaion)

Mobius: Single-handedly defeated the leader of Yellow Squadron
