Who has been better president of USA? Obama, Trump, or Biden? Politics and governments

Neither Trump nor Biden would be able to govern a country like the USA.
Trump is a liar, a fascist, an ex-president who has been convicted in court. And he is simply too old and too stupid.
His only concept is to keep setting different groups against each other and painting a dystopian picture of the future.

I mean Obama can’t legally run anymore

Trump is real i think
