[Batman] How much "better" is Batman Who Laughs than Earth-0 Bruce Wayne?

Batman who Laughs has killed many Batmen and has dominated a good chunk of the Multi-verse. With him setting his sights on Earth 0 Bruce Wayne, what does BWL have besides not having "no kill code" that Bruce Wayne of Earth-0 doesn't and vice versa.

If you were in a boxing match the point isnt to kill the other person, although it happens. The point is to outplay and outwit your opponent. 

If you are on equal footing with another person who is participating in this "game" its a fair fight. 

If the other person is on equal footing but has no issue eye gouging, taking your family hostage, killing innocents, weaponizing kids you are at a severe disadvantage unless you also adopt similar rules.
