Logical thinking is really easy for me. Also abstracting, pattern matching, "out-of-the-box" thinking.. Loyalty, honesty and helpfulness are also positive traits common among autistic people.
Having a unique worldview certainly is helpful in some situations. However it also makes other situations, especially pertaining to social interactions with strangers, rather challenging at times..
Greater general logical reasoning ability. Also, many people with ASD resent 'NTs' ((N)euro(T)ypical people), and view their existence with—not animosity, but as something they would not like for themselves.
For some people it's debilitating, but for others it's not.
