Well the one with APAP has
Acetaminophen in it, that is the medical communities reference for it. The other is just
Tramadol by itself, at least I am assuming such since you didn't mention APAP being with that one.
Which one works better for you, will be something you can only discover by trying it and giving it a couple weeks to see how much it works. There is no way, at this point, to know if you were really getting results from the Tramadol or from the Acetaminophen. They are both different types of nonsteroidal anti-inflammatories. Some people do respond better to one than the other.
Neither is a narcotic, so only trial and error will let you know which one works better for you. Everyone is different and what works for one person doesn't always do the same for another.
