Depends what you are referring to really. Compulsive behaviour isn't in the diagnostic criteria for either. Some autistic people really rely on routines and some of this can become compulsive. People with ADHD can become perfectionists so again some of this behaviour can become compulsive.
If it is a range of compulsive behaviours that are having a significant impact on life then it would be more likely to be OCD.
