do you prefer one over the other? why or why not? any advantages/disadvantages to one or the other?

I hear a lot of my patients saying they prefer flu mist, and one said they got the flu everytime after getting the shot, but not the mist, and the mist doesn't give you the arm pain like the shot.

I wish I had more time to research the two but I have to get the shot this week for school/work!
