Well Mr. Flamboyant just presided over 4 relatively stable years for the US, until the mess right at the end. Those final two months needed Trump to accept his election lot and concede, to have a better chance to try again. That chance has probably gone now.
For sheer idiocy, then I would go with the vastly experienced present POTUS, who seems to be ruining and harming the country, perhaps irreparably, with rash policies, insane military decisions and general stupidity. Biden seems to have learned nothing over a privileged 40+ year opportunity, Hopeless.
