If you like data, and I know you do, you can browse the adverse reaction database here:

Last I checked, Pfizer had 3X the adverse reactions as Moderna, which seems odd since the Moderna dose is 4X the Pfizer dose (100ug vs 25ug IIRC).
I think the Moderna design has a somewhat different delivery structure that allowed them to raise the dose level. I am not really knowledgeable in this area but here is one example paper with even a few illustrations:
