Is Agatha Harkness the most powerful?

While Agatha is a most powerful witch, she allies with others that possess great power to protect and guide them in the ways of magic. Two of her students include Susan Storm and Reed Richards’ son, Franklin Richards, and Wanda Maximoff, AKA Scarlet Witch.

Is Agatha Harkness as strong as Wanda?

While Wanda Maximoff AKA the Scarlet Witch is considered the most powerful character within the MCU, Agatha’s powers are enough to rival that of Wanda’s, nearly beating Wanda in their final battle in WandaVision. Part of what made Agatha such a powerful magic-user is her history with the Darkhold.

Is Agatha more powerful then Wanda?

Yes, she is more powerful than Agatha in MCU, she has Chaos magic which was supposed to be a myth and her magic is capable of spontaneous creation. That was the reason Agatha sent fake Pietro(Fietro) to know her secrets but she didn’t get the secrets. And now she has captivated Wanda’s kids.
