Taste is subjective. Cookie butter or biscoff may or may not be your cup of tea. It is not fair to compare it with Lily's or Ludy's as peanut butter has its own distinct taste. With peanut butter you get to savor the flavor of garlic roasted peanuts & sugar as with cookie butter or biscoff you get a combination of flavors of cardamom, cloves, cinnamon, ginger.
We have tried cookie butter and we love it. I agree that it is not easy to find and prices range from P380 to P500 depending on the seller.
With Lily's or Ludy's or any other peanut butter (lady's choice, etc.) it is readily available in the supermarket and prices are regulated.
Both are good on bread or on banana or on its own.
