I don't have the energy to research those specific meds right now (I did take an advanced college bio elective on drugs though).

But different stimulants have different mechanisms. Even within the same drug class, there are differences (like how effectively the drug binds to receptors, how long it works, how long it takes the body to break it down, etc). So it's not unusual to have different effects foe different meds.

As already mentioned, talk to your doctor about this.

Also do NOT take antidepressants with ADHD meds without first discussing this with your doctor. That interaction could be very dangerous, depending on which specific meds you're combining and other factors. Same with anxiety meds and alcohol.
