He was created to be stronger than hulk but most writers now write him as equal or below. Maybe hulk can eventually get to his strength but his base strength is negligible compared to thor. Thor is equal to Hercules, they have arm wrestled before and it was a tie, but they moved the planet out of its orbit from the force of it. I personally find that to be his best feat but most people use him lifting the midgard serpent, which was said to weigh as much as the earth, or moving Yggdrasil, or lifting Asgard. He's definitely way above 1000 tons
The Hulk and Thor have battled to many draws and marvel goes out of their way to not have a winner. Hulk has no upward limit depending on his anger so if its actual weight lifting , then it's Hulk who can be stronger I guess, but Thor has more raw power.
