Fake yhwach vs Yhwach from a thousand years ago

It’s implied they’re around the same level of reiatsu, but obviously the fake is weaker and will get one shot by the real Yhwach.

Yama didn't notice anything off about Fake Yhwach until the real one came in and had him exposed, so I think it's safe to say Fake Yhwach was as strong as 1000 ago Yhwach. I'd say 1000 years ago Yhwach has the edge due to experience.
