Pound for pound
Someone mentioned in another thread that Thor may be the strongest Hero on Marvel Earth pound for pound as the Hulk weighs more than twice as much as he does
So..... out of only hero's born on Marvel Earth, who is, pound for pound, the strongest... not Including Hulk (due to the whole impossible "unlimited strength" garbage)
I'd like to submit Ant-Man and Yellow Jacket for consideration:

Now Ant Man (and Yellow Jacket) are fairly fit and strong guys who exercise regularly... let's say Hank Pym can press 250lbs in the gym
As he's reducing his height by a factor of 150 his mass will be reduced by an even greater factor (as he's light enough to fly on an ant's back)
"suppose we scale up an ant by a factor of 1000. This increases the ant's length from 1/8 inch to about 10.5 feet It increases the strength of the ant's legs by a factor of 1000 squared, or 1 million. This sounds very reassuring until we look at the ant's increase in mass and weight.Each segment of the ant's body is roughly similar to a sphere whose weight is proportional to its volume given by the equation:
V = (4/3)pr3With constant density, the weight therefore increases with the cube of the scaling factor. Hence, weight increases by a factor of 1000 cubed, or 1 billion."

now scaling down would make the inverse of this true (i think) ... So Lang's mass would reduce by a factor of 150 cubed, or 3,375,000... taking him from 190lbs to 0.0000563 lbs
At this weight and his 250lbs pressing strength i believe this puts him at the top of the pound for pound strength category as he would be capable of lifting 4,440,497.336 times his own body weight
If he were capable of that feat at his 6ft stature he would be lifting 843,694,493.84 lbs, or 421,005.236 tons (taking one ton to be 2004 lbs)
