Natural immunity from which strain and how long ago? Does someone who recovered from the original strain 18 months ago have comparable protection to someone who recovered from Omicron yesterday? Or someone who has been vaccinated? We do not know these answers.
What we do know - based on mountains of data - is that vaccinated people take up hospital beds far, far less often than unvaccinated people.

Doesn't matter. If you have already take the vaccines, it is my opinion that it is better to get the omicron variant and have natural immunity, (unless of course you are particularly vulnerable).
Your point that vaccinated people take up less beds is exactly right. Omicron is a highly contagious, weak strain and would provide and amazing opportunity for mass natural immunity, without the fear of hospitalization and death.
