Why is that? I'm in the biotech field and I hardly get any sense of one being better than the other? Is such knowledge spread via social media? (Which I avoid)

Unfortunately there is huge difference when it comes to the South African variant. AZ no longer works, but Pfizer does:

The 2nd key reason is that no other vaccine is backed up by so much real world data as BT because of Israel. That is the very topic of this thread. That is why I thought it is self-explanatory.

I think that's because the initial announced efficacy for ModeRNA/BioNTech was 95ish%, whereas for AZ it was 75%.

No, because AZ does not work against the SA variant of the virus, but BT does.
