Just looking at the Wikipedia pages for each pandemic, the Spanish Flu is "generally accepted" to have killed 25 to 50 million people. The Wikipedia page for COVID-19 cites a 2022 The Economist article that estimates 18.2 to 33.5 million death toll for the COVID-19 pandemic.
Of course, the world population was probably less than a quarter of what it is now, so a higher percentage defintely died. Probably because of the relatively crappy health care at the time
