Not all chili crisps are the same.  Momofuku is the gold-standard brand in that department.  Others can range from "close enough" to just bad.  The only one I've ever found that was FAR superior is a little ma & pa outfit in metro Nashville that no longer produces their version.  It was delicious.  My sister bootlegged us a bunch before they stopped making it, and I'm close to finishing my second-to-last jar.
