Disc brakes are spinning saw blades, and have killed people. Then again, with rim brakes if you get one drop of water on the rims, you will be unable to stop and will careen into oncoming traffic. Disc brakes have way better modulation, whereas with rim brakes once you press the lever, your wheels will lock up and you will endo. Disc brakes take a degree in astrophysics in order to adjust or change the pads, whereas rim brakes can be adjusted by a trained monkey. Wheels with rim brakes are easier to swap, for the next time you race in the Tour de France, whereas if you have a disc wheel, there is exactly one wheel the pads will work with, and anything else will not fit.
I think that about cover the pros and cons. The choice is yours.
