Superman can hear a single human heartbeat and distinguish it from all other humans on the planet, from space.
This is no contest, Supermans hearing is far superior to DD. I would say he has better smelling senses too. As for touch I am not sure as everything is like paper to him but it would still make sense that it is better if he can touch things without breaking them, the control needed is immense.

This reminds me of my, "Who's more agile: Superman or Spider-Man?" query. We see Spider-Man doing acrobatic dodging and such all the time, whereas we rarely see that from Superman. But given speed is a big part of agility, one could only conclude that, in an agility contest, Spider-Man is left in the dust.

Superman, no contest. He can hear things from interstellar distances and when you count how invulnerable he is, his sense of touch is truly remarkable.
Superman can hear the heartbeat of entire planet at once and pick up individual heartbeat among them.
I've seen a few sense of smell/touch feats that were good for Preboot, but can't think of any ridiculous. Mostly because it was rarely touched on(but with as many comics he appeared it they had to happen). Got any examples?

Pre-reboot can see, hear or smell anything on the planet and in some cases even science-bending. [Like seeing across the solar system in real time, hearing grasshopper heartbeats in beijing - from space, etc]
