I am 8 and 9, with a small touch of 10 whenever I want to RP.
I control everything, but that can get tiring at times #9.
However as for #8 I prefer to make them act on their moods so if their whims say kick someones ass, they will do it,
HOWEVER if they have certain traits like evil, they will do EVIL things, like killing other sims for example...
Which is why I wished evil sims can get jailed for the crimes they commit... D:
As for #10 I do that on a alternate save file with a combination of #8, just to see how their life plays out, sometimes it can be boring, sometimes it can be interesting. :D
