It certainly differs depending on the person and the way they view their disability.

I am autistic. It is a fundamental part of who I am. Had I not been autistic, I would be a completely different person with different mannerisms, interests, habits, and so on.
It is for this reason that I, personally speaking, prefer the language “autistic person” over “person with autism.” Autism is a condition that fundamentally changes how my brain works. It is inseparable from me.

Of course, this only speaks to me and my autism. Other autistic people, and indeed other people with different conditions, may prefer other language.
