The data is sourced directly from your Google Search Console account.
Some SEOs call it the the "only source of truth" for SEO data.
The fact, that this is data coming from Google directly gives it a main advantage over any third party data.
However, that doesn't mean it's perfect. No data source on the web is perfect.
