This is tough. Not the match, Krillin easily wins. The hard part is convincing everyone else who didn't watch the show completely. Excluding GT of course.
Lets take a look at something we can measure. Speed. We can say that Krillin is at least as strong as Goku or a few less, when Goku made it back from snake way. Snake Way was described as 1,000,000 kilometers(621,371.192 miles). From when he was finally wished back to life, and to when he finally got back to earth, let's just say he made it in 24 hours.
621,371 miles/ 24 hours = 25,890 mph.
Hell, let's say he took 3 days. 621,371/ 72 hours = 8630 mph.
Let's get crazy: 7 days. 621,371/ 168 Hours = 3698 mph.
Alright, so he's fast, so what? Going at those speeds, all Krillin has to do is fly.
Take him underwater. For something, anything, to be able to produce the speed of 3698 mph(61 miles per minute, 1 mile per second) must be able to produce enough power to escape the depths of the deepest body of water.
Durability, a body sustaining itself at those speeds without breaking, is a sturdy piece of material. We can see Goku flying at these speeds all the time, yet he is not phased at all by this.
I don't see aquaman being able to compete with Krillin in any situation. Maybe if Krillin was unable to escape from water, stretching 183 miles long in any direction.(That's about 3 minutes of holding his breath)
Krillin wins it. And that goes for you too, Superman. Goku better win Deathbattle.
