Do you have a professional or personal preference favoring Pfizer over Moderna or vice versa?
My two adult daughters have both been vaxxed, one with Pfizer and one with Moderna. The Pfizer one had markedly more soreness/fatigue with the 2nd dose than the Moderna one did.
They didn’t get to pick and choose since they were in the first wave of medical workers.
I do not believe there is a substantial difference.
In the beginning, Moderna had an edge because of the -80F requirement for Pfizer (and the chance the shipper/storage facility would screw it up).
