I've never had Focalin but seeing as it's dexmethylphenidate, I think I can assume it's functionally quite close to racemic methylphenidate (Ritalin, Concerta).
I've only had Adderall once but seeing as it's 75% dexamphetamine (which is by far the superior isomer), at least I would go for it without question. I've had racemic amphetamine and Dexedrine (pure dexamphetamine, Adderall has 25% levoamphetamine) and for both functional, therapeutic purposes and recreational highs they are far superior, both in my book and according to everyone I know.
That said, I don't find either methylphenidate or amphetamines in general to be highly recreational. High doses are slightly recreational but not worth it in my book for the side effects.
