I certainly don't think having a diagnosis elevates anyone above another, it is merely an outside perspective that can be valuable, perilous or useless depending on your situation.
In my case, while I had heard of Aspergers and Autism, I really didn't know anything about it until it came up in the course of seeking help with high levels of anxiety, sleep problems and a growing feeling of being oddly different, out of step. I guess I was too busy being engaged in my interests, or dealing/not dealing with the effects of my "problems" (ie. wildly inconsistent academic performance, failed relationships, being taken advantage of, being misunderstood, underemployment, substandard living conditions, uncertain future) to have the presence of mind to self-diagnose. Once it was introduced, I set out to research all I could find on the subject, seeing myself in much but not all that I came across. That, along with a formal assessment and diagnosis, has allowed me to accept that, yes, I am an Aspie. I am only recently beginning to see how that knowledge will be helpful to me going forward. May that bring some relief and happiness.
Actually, it wasn't until I dipped my feet in the waters of psychological therapy that I felt there was anything really wrong with me, I just thought I was one of those people who saw the world and existence in a different way than the norm, and that had a strong influence on my lifestyle. Some people like that seem to be able to lead happy and fulfilling lives. In some ways, I wouldn't mind going back to that state of being, as I feel I was much closer to being happy and fulfilled than I am now. Too late for that though.
So, however you get there, embrace the understanding you gain about the problems you have in living this life. It's a tough path, we are here for each other.
