They are the "safest" ones I've found, anyway. I've seen no autonomous behaviour from any of them, except visitors trying to fix my stuff when it breaks. And that's not a problem, as long as my sims handiness is maxed....if not, I'll quickly reset the sim and repair the object myself (or my sim will....).
Oh and I forgot: in Evergreen harbor, you have the Green/Modern Initiatives. I've not seen any issues with autonomous behaviour with those, either. I just don't have many sims living there, so I forget they excist.
