Excluding the halo of the protagonist, who is stronger, Zero, Orb or Geed?

I think Ultraman Zero is the strongest among the three Ultraman Zero, Orb and Geed, excluding the protagonist Halo.

I usually like watching Ultraman very much. I have watched many different Ultraman. Among these three, I think Zero is the strongest because Zero inherited Seven. He has a lot of abilities and skills, and he also has a head dart weapon, and his fighting ability is also very strong. He studied under Ultraman Leo and learned Leo's famous stunt, Leo Flying Kung Fu. Remarkable.

So I think the other two Ultraman can't beat him.
