Which Acne System is better?

Hello i would like to know which acne system is better Proactiv or Skin Id? or any other system you can think of. I currently use just L'OREAL and before Neutrogena.But L'OREAL hasn't really worked for me or i don't know if its because i don't watch my face every day in the morning and night because of school, i used to though. I really like Neutrogena but im not sure if it actually works. I've heard bad stories about Proactiv and i don't know if they are tru. But i really like Skin id bc it is from Neutrogena but i would like you for you guys to tell me which one is the best. I don't have horrible acne. Just a pimple every now and then, and blackheads, but thats the only major thing. Im also only in high school if thats helps in any way. Thanks guys so much.
