I don't think there was as much pushback about his policy as much as there was discontent with an economic slowdown and a somewhat ironic (considering where we find ourselves) frustration with his age.
But yes, people dislike Biden for a lot of things he didn't deserve to be disliked for, such as inflation which was caused by COVID and Trump and which Biden did a fantastic job of controlling, but which parts of the public simply perceived as "inflation went wild under Biden". Still, even though it's not fair, the message "I will do nothing different from (unpopular incumbent)" isn't great campaign strategy, in my opinion.
Because we have a true dichotomy I don't think it's reasonable to assume that trump had any sort of "policy" win there
