Good vs bad is subjective and some people might disagree. For instance, many in Trump's base are happy that he separated children at the border from their parents as a form of medieval punishment to immigrants seeking asylum.

However, here are two pages that I find important. Here is a super tiny list of Biden's accomplishments, keeping it to only 30 for brevity: https://www.politico.com/news/magazine/2024/02/02/joe-biden-30-policy-things-you-might-have-missed-00139046

And since there's so much negative to say about Trump, given that he is a criminal with bankrupt ideas and tons of problems, here is one link that focuses on economics: https://www.propublica.org/article/national-debt-trump

I like to summarize Trump's ability as a president with this simple example: Trump is the only president to have ever promised to completely wipe out the US national debt. The reason other presidents don't promise this is because it's stupid, no country should operate without debt. An economist should know that, BTW, and he is constantly remind us that he graduated in Economics from a top school, while he doesn't seem to understand basics of macro economics. Then, once he became president, he added the most debt in a single presidential term in history. So he campaigned on a truly stupid promise to completely wipe the national debt, yet he then added the most debt ever.

That's the kind of president you get when you vote for Trump. As Rex Tillerson said, a man that doesn't seem to comprehend what the adults are talking about and doesn't even understand why the adults want to talk about it. A fucking moron incapable of presidential decisions. That's in addition to all the horrible stuff he brings with his nasty personality, corruption, crimes, and so on.
