I felt this was interesting question because KH has dabble into both even during final boss sequences. I think my preference is humanoid bosses because it feels a bit more realistic in a very unrealistic world. Maybe Days scarred me on giant monster type battles but they don't feel as engage as fighting something human shape.
So I might be a bit perturb if during the final fight Xehanort turns into some darkside/Guardian hybrid giant that Sora needs to slay.
