What DriGuy said, almost exactly!
I don't see these as either/or propositions. Why go "alone" when there is info to be learned, things others do that work we might not have tried, friends to talk to who get it...? I believe that using every available "thing" to build my perfectly imperfect sober life is worth my time and attention.
"Take what you want and leave the rest" is an AA mantra that rings true for me in this context in particular- I don't believe the steps are "optional" or a cafeteria plan, but I do believe and know from ongoing experience that some things resonate with me more than others. And that extends beyond AA to the rest of the everything in the everywhere!
I also look for the "people who have what I want." Looking at and comparing things to "the many who do it alone" (para your words) isn't really a worthwhile thing to me - kinda like NOT stacking the odds in my favor, so to speak.
Whatever you do - whatever works- keep doing it.
