I'd probably go with Fire. Screw you guys and your matter, I bend pure energy. Even without being able to bend lightning (which would be useful), a clever fire bender would be able to do something interesting things with the right application.
Water bending intrigues me though mainly because of blood-bending. That would be incredibly fun to have.
