The amount of acetaminophen in each is similar (300-325 mg) and the main difference is the amount of opioid pain reliever (codeine - 30 mg/hydrocodone - 7.5 mgs). It may seem that you're getting more of the opioid pain reliever with the codeine but since hydrcodone is about 5 x's stronger you're actually getting about the same amount in both...
So far as pain relief they're both quite similar.
