Yeah if I need to I take both also. In addition I be sure to have a caffeinated drink also as caffeine has been shown to both speed the absorption and boost the efficacy (5-10%) of paracetemol over a multi hour period. https://pubmed.ncbi.nlm.nih.gov/17442681/

> Does ibuprofen work better?

In my experience it works far better at managing headaches/migraines.

There seems to be some percentage of people that acetaminophen seems to do very little for. Ibuprofen has a much more pronounced effect, to the point that I take it at half it's recommended dosage.

For inflammatory pain (most headaches, most pain from injuries), ibuprofen absolutely works better. For migraines, neither works at all on its own -- though ibuprofen plus caffeine (I generally drink tea) does a little. For overexertion aches and cramps, or fevers, I think either is generally fine.
