Why do we need Lighthouse at all when Google also offers similar reports in PageSpeed Insights (PSI)? CrUX data is important because it is how web core vitals are measured, which, in turn, are a ranking factor for Google’s search results. The reason for the distinction is that there are different ways to throttle a network for testing.
