Considering that both Khezu and Gigginox were designed to be creepy, and that Gigginox pulls it off a lot better than The Penis Monster does, that adds extra points in Noxie's favor. Gigginox's design is more realistic and shows how much more effort Capcom put into designing a legitimately scary "cave wyvern". She actually looks like something that's perfectly adapted to living in caverns, whereas Khezu is just a plucked turkey with a leech head.

As several people have said already, Gigginox actually has music, which is a massive plus.

Additionally, the battle with Gigginox is a lot more dynamic and exciting than the battle with Khezu, which mostly consists of him spamming the electric orbs that go through walls and assaulting your ears with that God-awful scream of his. Gigginox feels like a challenge, while The Penis Monster is just boring and cheap.
