Dry weather?
Would you rather jump off high speed metro train or airplane?
Airplane, seems like it'd be quicker and more fun. Plus you never said the airplane was moving so I might survive if it's pre-flight hehe.
Would you rather gain the power to:
a. Make every inanimate article you touch become extremely lucky, but the thing in question will spontaneously explode with the force of a box of TNT anytime from 5 days to 5 years after you touched it, or
b. Teleport through people's dreams to wherever you need to be, but you gain a small part of each dreamer's personality as a "shade" that follows you around and tries to influence your actions for a week.
