Depends on what you mean by aberration. I voted Trump because he's clearly the more unorthodox president and a break from the kind of people we would normally expect to be President, people like Biden.
But if you mean whose legacy will actually last the test of time, and who was the exception to a broader trend, that will be decided by the 2024 election. Both will have served one full term, and if Biden gets a second term, then Trump will be seen as a weird aberration that took over the GOP and squeaked out a win against Clinton, but lost re-election, lost re-re-election, and didn't do his party many favours downballot. Basically a textbook example of a failed president. But if Trump wins, then he will be seen as a more significant figure, and Biden basically a remnant of a bygone era who didn't accomplish much and was not suited to the challenges of his time.
There's an argument to be made that many of Trump's ideas (protectionism, onshoring, "America First") will be enshrined in Biden's legacy even if he is reelected, considering that Biden has arguably done a better job of putting them into practice. Whereas if Trump is reelected and the US's standing declines further than it would've had Trump not been reelected, Don Giovanni would also be seen as a pivotal figure in that outcome.
