Even taking the data least charitable to my postulate, a study[1] (which there are issues with that I will not mention) using a sample of 63 million medical records found a reinfection rate of 0.48% compared to 2.2% infection rate for the previously uninfected.

This study therefore estimated protection against reinfection was 78.8%.

That's higher than the 72% efficacy offered by the J&J vaccine.

Potentially all the vaccines; the Moderna and Pfizer vaccines were tested before the emergence of variants. The J&J was more effective in the US where fewer variants were present at the time of testing than internationally where the opposite was true.
