Determining what medicine to start with is a very active research topic. If you're very hyperactive, perhaps stimulants are the way to go. If attention deficit is the dominant factor, perhaps try non stimulants first. They pose a lower risk of addiction and supposedly lesser side effects, but that is very dependent on pacient and specific medicine.
Obligatory I'm not a health professional and this isn't medical advice. Your psychiatrist is the best person to answer these questions.
