I always play with full autonomy on, but I often have to go in and steer my sims into doing things. They often just sit at the TV or computer if I leave them to themselves. They never leave their apartment to go out to the square below, or outside their yard if they live in a house. So in my experience, full autonomy does too little and I would like so see my sims actually do more things and take more decisions by themselves. They rarely flirt, argue, seek out a lot of conversations or such by themselves. They don't even care for their own needs very often without me having to tell them.
