No one here will be able to say what's best for you, this is something you need to figure out with a doctor.

I think you should talk to a doctor. Everyone reacts a little different to meds so ymmv

Check with your doctor. Everyone is different. Some may work well but with nasty side effects.

Even different generic manufacturers of the same medication will react differently in the same body.

Talk with your doctor, try them until you find something suitable. And, respect the posology and dosage. This more important than you could imagine.

You should take what works for you. There's no "this drug is the real one that works."

Each drug has differences in the way it works and the effects on an individuals brain chemistry.

A psychiatrist would start you on a low dose of a given drug and increase dosage while monitoring impact and side effects. There's no good way to find the best drug for you without literally trying them all. But that's a long annoying process, and I think most people just stop trying when they find one that's "good enough."

They are quite different molecularly, Concerta is extended release methylphenidate (instant release is Ritalin) while Adderall is instant release dextroamphetamine and amphetamine. But there's also extended release Adderall too. All in all, it'll come down to your specific neurobiology regarding the best treatment option. However, if appetite suppression is a concern for you, using an instant release med will decrease the amount of time the med is active, which should reduce the duration of any appetite suppression.

This comes down to your individual biology. Everyone reacts differently to different medications.

Echoing other commenters; this is best determined with the oversight of a medical professional.
