It depends on the Zoan.
Any insect ones can be really shitty if you are the size of a human already. The Human Human fruit only makes you smarter if you are already a human to begin with.
Carnivorous, Ancient, and Mystical ones are clearly the best Zoans. Miscellaneous ones like Model Giraffe and Model Tanuki (Yes, Tama’s teapot “ate” this fruit) are just wildcards.
