It seems obvious to me.

To hopefully add some nuance, there are potentially two related questions here at the heart of why people ask if natural immunity is stronger, though both have roughly the same conclusion.
1) is it better to get vaccinated or catch COVID naturally if I'm young and healthy?
Answer is a resounding, get vaccinated. It's safer and has more reliable immune response. Much of the data on immune response from catching COVID are among those with symptoms, sometimes even moderate or more. If you have very mild or asymptomatic responses, you may not achieve the level seen in many recent studies. So, higher risk and really unknown probability of benefits.
2) Do I need to get vaccinated after catching COVID since I probably had a robust immune response?
The answer is still get vaccinated. It still massively boosts your immune response even if you've had it before and even if you have detectable antibodies.
I'm not telling you anything new, but wanted to add the questions that seem to be behind the natural immunity vs vaccine questions.
