When one is infected, there is not determining which epitopes the immune system will use to trigger on. There have been many clinical trials, in many countries, and they all show that the vaccines produce longer lasting, broader immunity. Of course, those who recover from a Covid infection, and then get vaccinated, have the best immunity.
(Also, there is a lot more to the immune system than just T cells and B cells. There are a whole battery of different white cells, with unique functions, not just lymphocytes. Don't discount cellular immunity. Humoral immunity is not the totality.)
