Which is spicier wasabi aioli or sriracha aioli?

Wasabi aioli is generally spicier than sriracha aioli due to the pungent heat of wasabi, which can create a sharp, intense sensation. Sriracha, while spicy, has a more balanced flavor profile that includes sweetness and garlic, making it less overwhelming in terms of heat. Ultimately, the spiciness can vary based on individual preferences and the specific recipes used.
