As someone who is fairly well-informed on this issue, I can say that it has been disastrous. If you are actually interested, I can explain or at least link to some articles. A good starting point is this one that was posted earlier in the thread:
This spring, a team working under the president’s son-in-law produced a plan for an aggressive, coordinated national COVID-19 response that could have brought the pandemic under control. So why did the White House spike it in favor of a shambolic 50-state response?

The information in this article shows that the administration wasn't just wrong in their response -- they may have been intentionally wrong. What's more, they actually had a valid strategy (one that experts and epidemiologists would consider a fairly good approach) but did not execute it, either due to politics or due to incompetence. What's more (the article doesn't really get into this), they have dropped the ball at nearly every juncture, starting in December/January, again in February/March, again in April, and again in the summer months. Not only has this resulted in unnecessary loss of life, it has prolonged the damage to the economy (the only way to save the economy is to stop the virus), it has put us in a worse position moving forward (more people infected = more difficult to open anything, more difficult to test, more difficult to trace, etc.), etc. etc. These kind of things require leadership to be proactive but instead the administration has not just been slow, they have been late (for example, shutting down travel from Europe AFTER it had already spread was kind of pointless). These things require leadership from the top (local leadership is helpful but not enough), but instead we have gotten nothing of the sort.
We can potentially argue about whether the tax relief plan a couple years ago helped the economy as there may be uncertainty to the data and a lot of politics involved, but in this case we have a clear cut public health disaster and the analysis is one of science, not politics. There are of course some gray areas, some discussion about the optimal strategies, but none of them overlap with the way this administration has handled the pandemic.
