I'd pick teleportation, preferably some variant where I can appear where I am looking, and/ or that one in Jumper where you can look at a photo and show up where the picture was taken. I would like to travel with this, use it to play pranks, explore, and I'd be unstoppable in stuff like paintball, and if I went skiing I wouldn't have to ride the lift. Also, I could use it to get around work faster and avoid people and things I'd rather not deal with. It would also be invaluable for escaping immediate danger. You can't maul me, mister bear; I'm already back at the lodge drinking whiskey.
