To be practical I would need some more info on the invisibility aspect.
Could you walk in to the bank / CIA headquarters / whatever and walk out with the Gold Bars / Top Secret Documents / Whatever.
If you can't render objects invisible then its usefulness is very limited. In cold weather your teeth chattering would give your position away.
X-ray vision is likely unnecessary if you have either of the other two.
Speed is dependent on what you can do with it.
OP, we need more details before we choose. Does speed speed up your aging process. Can you turn invisibility off.
