Do you prefer Pampers or Huggies, or another brand?

We just joined Costco this weekend in anticipation of needing to buy LOTS of diapers soon. Anyways, they only sell Huggies, which I've heard a lot of people say leak too much. They also have their own store brand, Kirkland, but I haven't heard anything about whether or not they're good. The prices seem really good for both brands, except they only have newborn size in the Kirkland brand. What kind do you prefer, and where do you shop for the best prices?
