I'd say download both the PDF and the XML. The PDF is easier to read, but the XML has more information. In particular the XML shows earnings for every year. The PDF shows earnings for several recent years, and then from groups of years before that. I don't know if it is the same groupings for everyone but mine is grouping 1966-1980, 1981-1990, 1991-2000, 2001-2005, then the individual years up to 2024.
