I like the AI personalities for the potential that you WON'T be able to do what you want and you'll lose sometimes, and have to deal with the consequences.
I don't like unexpected surprises at all. Generally I have playthroughs dedicated to chaos and wrecking things but not many of those, outside of that it's always a constant search for the perfect playthrough....best choices both in main and side quests, 100% completion, best character setup and gear, etc. And all it takes in one conversation gone wrong to completely ruin countless hours of work.
