I continue to attend meetings despite the fact that there is no active addiction or alcholism in my life right now. I go for _me_ and find that it's where I need to be to learn how to take better care of myself, learn new ways to cope with life and begin to untangle years of accumulated 'stinking thinking' and bad habits.
What I gain from my meetings is priceless....well...I do drop a few bucks in a basket, but it's still a good 'deal' for the amount of money...especially when compared to therapy.
Therapy is good, I've benefitted from it a great deal, but these days I find exactly the help I need in Al-Anon. It works for me.
You could try attending both fellowships for awhile and see which one you like the best.
