I just checked my website speed on both analyzer, there are mass differents, like speed index or LCP, in GPI my website archive the maximum score but when use Lighthouse, my total score went down like 20. I don't know which tool provide more accurate results, because in real world, on any device, my website work very fast, similar to GPI result.
 
Both are great tools to check website performance and improve it accordingly.
However, both tools don't work on the same metrics to provide results or insights.
GPI combines real-world user data and lab data to provide the overall data so for a better understanding. GPI collects real-world data from the Chrome User Experience Report.
On the other hand, Lighthouse provides broader analysis based on lab data including accessibility and SEO.

I suggest to analysis the metrics of both the tools and make changes in the website accordingly.
 
Both tools offer valuable insights, but real-world testing across different devices is key to truly understand your website's speed performance.

Depending on your specific needs, one tool may provide better results than the other.

But both the tools provide better results.
 
Both Google PageSpeed Insights and Lighthouse are tools provided by Google to assess website performance, but they evaluate different feature. PageSpeed Insights focuses more on user experience metrics like Core Web Vitals, while Lighthouse provides a broader analysis covering performance, accessibility, SEO, and best practices.Both tools are valuable for evaluating website performance.

Don't stress too much about the exact scores.Both Google PageSpeed Insights and Lighthouse give you an idea, but the main thing is how fast your site actually feels to people using it on different devices. Look at both to get the full picture
 
Both Google PageSpeed Insights (GPI) and Lighthouse assess website performance, but variations in metrics, testing environments, and algorithms can lead to score differences. Both tools offer valuable insights, so consider specific metrics, prioritize optimizations, and test across devices for a comprehensive understanding of performance.
