As an example of details: Lina Khan as FTC chair under Biden did more for true public good and holding the oligarchs to account than any other political figure in 50 years. If there were no other differences between two directions except having or not having Lina Khan, the difference is still massive. And there are tons of other differences.
Personally, most of my time is focused on the bigger-picture issues, but those are also the hardest to change.
