The Pfizer and Moderna mRNA vaccines seem to have strong evidence of being more protective than other options. The AstraZeneca vaccine has some early evidence of not being protective against the South African variant and has some minor safety concerns around extremely rare blood clotting. As far as I have heard anecdotally, the mRNA vaccines seem to have stronger flu-like symptoms, especially for the second dose. If you are in the USA you should be able to easily choose between the three approved vaccines, so it is relevant to gather good information, just as you would with any medical decision.
