To be fair the flu kills those with other health issues - like this does. So if you were only to count those with the flu and no other major health issues the flu death rate would also be much lower.
The data is so scewed up who knows which kills more.
I'd guess Covid-19 is is worse than the common flu - but not drastically. And I say that based on a small number of healthy people that respond very badly to the Covid-19 that have survived the flu up to that point in their lives. There appears to be a genetic predisposition in some people.
