That's a but unfair for Zamasu, the only thing Merged does is debuff your allies and hits hard on a Potara or ROG lead.

Jiren can stun all allies, hits very hard, is a Category leader, and has a 10% greater boost than Zamasu's own ATK buff and also boosts their DEF as well, and guaruntees a critical hit against a stun enemy.

There's no competition, at all.
