I would want the ability to pause time. What would you want, hubski?
Telekinesis - The ability to manipulate matter from the atomic level up.
Think about it. In a fight with Superman you simply prevent his nervous system from sending electrical signals, you break the strong force holding the atoms in his body together, you prevent the blood in his lungs from absorbing oxygen....... The ability to manipulate the universe around us by force of thought, it trumps everything else.
Alter matter around me at any scale and have the knowledge to take full advantage of it.
I'm going to agree with you. Pausing/stopping time is the perfect superpower. Definitely the most practical in real life (provided that you do not age or feel tired/hungry/thirsty while time is stopped). Need to get something done? Yeah, that'll take literally 0 seconds in the real world. All the unexciting things you want to do in life can be done without wasting any time. But, you could also do so much exciting stuff with paused time like going on a hike across the world or something. Furthermore, it would be nice in a superhero battle. Someone turns invisible? You've got plenty of time to find them. There are, of course, some boundaries that need to be defined for this superpower, but without a doubt, it would be awesome.
