I'd choose Pfizer because AFAIK this is the first vaccine Moderna has ever made. At least Pfizer has some history, even if both are using a new technology. Also, anecdotally, the Moderna shot seems to cause more side effects. But I wasn't given a choice, and I'd happily get J&J if it was "this or nothin." So I ended up with Pfizer anyway.
