both wouldn't be happy if you wanted actual democracy (like economic democracy for instance). both will utilize the police and alphabet agencies if they will find it necessary. PRISM was exposed under Obama. Democrats Kennedy and Johnson did not stop COINTELPRO. I'm not even convinced by reducing this to which of them will be weaker and less competent, like you realize the senile octogenarian Biden would fit the description, but that actually makes it easier to control him. Trump on the other hand is harder to control for his own trustees, but at the same time would mean way less stability. Ousting either along with the whole system that brought them into power is a must and I'm quite convinced that it will not be an easy task in either case, especially if you consider that the police force is always a fertile ground for all of the most disgusting trash of the ruling class, like homophobia, racism or hatred towards the poor. Democrats can promise defending the police but will they? Or wouldn't that be shooting themselves not in one foot, but both?

And lastly, speaking of another Trumpist coup. The situation in the US is not yet comparable with e.g. Spain in the 30s. But back to Biden's incompetency, y'all should study how the Azaña's government absolutely botched the coup in July 1936. Then the lack of sufficient cynicism towards the government with "anarchists" taking ministerial positions and disarming the workers was what largely contributed to the Francoist triumph. With no illusions towards the government, there would be no mechanism to blunt the militant social tensions to come but force. And if you are afraid to actually fight for your ideas, you're already unfree.
