Are my decks too close to cEDH?

I’m feeling unsure, as someone said my B4s are basically cEDH level decks, so I thought I’d ask the experts. These are my three B4s:

Kefka: https://moxfield.com/decks/3KoKXk2ly0yixXQWcGVW9g

Rowan: https://moxfield.com/decks/9maV0EGXz0i6BuYNgjzF\_A

Hidetsugu & Kairi: https://moxfield.com/decks/V5meAZlwqnSnlEfi4k2jSw

Kefka and H&K were started from budget builds that I’ve been changing up and upgrading over time, Rowan I built from scratch. Are these too powerful for B4?

Note: I know very little about the cEDH meta, because it’s not something I look into outside of one time I proxied a Thrasios/Vial Smasher deck and what I’ve seen at my LGS.
