The list of inbound links on Google Webmaster Tools is generally much larger than the list of inbound links that can be discovered using the "link:example.com" search query on Google itself.

Google Webmaster Tools, as well as the Google index, seems to routinely ignore link spam.
Once a manual penalty has been removed, Google Webmaster Tools will still display the penalty for another 1–3 days. After the Google Search Console rebrand, information has been produced demonstrating that Google Search Console creates data points that do not reconcile with Google Analytics or ranking data, particularly within the local search market.
Due to a persistent bug in the new Google Search Console, many users cannot upload a valid sitemap ("Couldn't fetch sitemap" or "Sitemap could not be read" errors).
