H1N1 had 18,500 confirmed deaths. Covid 19 currently has 11,400 confirmed deaths and accelerating. I would say Covid 19 is a lot worse. This isn’t your Grandfather’s influenza.
I am not saying the world is coming to an end or that everything should be closed and everybody sent home from work, smashing the economy. But yes, Covid 19 is a different worse animal than SARS or H1N1. This is a very bad one.
The 2009 H1N1 flu had approximately 14,000 deaths in the United States. Data is a bit specious (varies from about 12,000 - 18,000 depending on the source), but that should at least be in the ballpark.
There were 150,000–575,000 2009 H1N1 fatalities worldwide. The Covid-19 deaths (”11,400”) you are quoting are the worldwide - not USA - deaths.

Actually CDC says 274,000 for H1N1 but possibly up to 579,000 globally. Its in my comment section and at the virology link provided.
