All three are good. Use Ice Cat in red-heavy levels (Red Alert in later SOL, notably), Catman against his specified types, and Amaterasu against mainly anything. As a general lineup, I would choose Amaterasu because of her flexibility. Catman and Ice Cat are specialists and are good for targeting specific enemies.
