Current peer-reviewed published info indicates vaccines confer better immunity than infection. There is an Israeli paper hanging around out there that is not yet peer-reviewed, we'll see what happens there.
It seems to me we still have little understanding of which antibodies interact with which virus proteins. So I'm trying to understand your statement re: S-specific ABs only attacking one type of spike protein. Do you have an article or paper to reference?
I asked for a reference, so I'll provide one also. This is a good overview of the current situation. Of course, this will evolve over time.

That's not true. Acquired or natural immunity often can last a lifetime. They say you never catch the same cold (coronavirus) twice because you acquire natural immunity. However, there's also dozens of mutations and variants of the common cold so that's why we still catch colds every year. It's will be the same with Covid. If the vaccines conferred strong immunity you wouldn't need booster shots every few months. Pfizer admitted their vaccines waned by summer. As for Israel, they're already working on their fourth booster shot as cases continue to go up.
I will try and link the S-specific protein data later. It stands to reason, anyway, as it was developed for the original Covid hence it doesn't work that well against variants. It's not even a vaccine, remember, it's mRNA gene therapy. It instructs your cells to recognize and neutralize a particular spike protein.
