I think it's pretty clear that in better times, neither Trump or Biden would be the nominee for their respective parties. As it stands, in today's unstable and confusing world, they are the only two practical choices and this is why I feel Trump is the better choice.
Trump is an unusual candidate but he is the incumbent and under his administration, pre-COVID, the US economy did have extremely low unemployment numbers and the stock market was doing well. GDP growth has also been relatively strong. Historically, state of economy tends to be the top concern for most Americans so he has a good record there. He has lowered income tax for almost every American by 2-4% depending on your tax bracket. He also offered a one-time 15.5% tax window for Americans corporations to repatriate. He also passed the First Step Act, a prison reform bill that's definitely a step in the right direction. While he wasn't able to build a wall with Mexico like he claimed (I doubt anyone actually believes that he would've been able to achieve that), illegal immigration has indeed gone down during the Trump administration (you can look at Pew for this data).
On the downside, you can argue that his Presidency has brought out a lot of racists out of the woodwork but this isn't unique to the U.S. If we look at global politics, many countries have been shifting to the right for numerous reasons such as refugee crises, illegal immigration, outsourcing, poor economy, etc.
In regards to the current state in the U.S. (massive protests & racial tensions), a lot of what's been going on is not the result of any single administration, but decades of poor treatment towards the black community. That being said, a lot of people, minorities included, are NOT happy with the way some protesters are destroying property, looting, and destroying cities. During these trying times, you see mayors like de Blasio (a Democrat) defund the police and march with the protesters, leading to a spike in crime in NYC and a vote of no confidence by 150 business leaders of large corporations, who claim NYC is on the decline as a result of his policies (and many of these leaders have supported Democratic candidates in the past). Lawless/no-go zones in a lot of Democrat-run cities such as Seattle and Portland are upsetting a lot of people for good reasons.
At the end of the day, most decent hard working folks just want their cities to be safe and earn a good living. The Democratic party has shifted so much to the left during this election that I can't align with their policies, and I am skeptical that they can do a good job by dividing communities (i.e. everyone who doesn't support me/BLM/radical left is a bigot/racist). Instead of focusing on what they can do to solve the current issues, they pander to certain groups and the radical left, and focus their efforts on attacking Trump. This is poor leadership.
