There are a lot of other options. Rational Recovery, etc. There is a secular section here on SR. I have gained a lot of knowledge and renewed belief in myself there. I do use parts and pieces of AA and I do believe in a Higher Power but I enjoy all of the avenues to keep me strong. I like to be able to talk to my Addict/Alcoholic voice and tell it to STFU.
I am in the camp that whatever keeps you clean/sober.
