I like my light side SW just now. She is essentially more honour driven than anything else. Also I'll do anything if it annoys the likes of Barrus and Kilran.
My assassin varies wildly in choices, depending more on how I feel at the time. This makes her seem more unstable, unpredictable and quite psychotic, which I find more entertaining and fitting.
I have never experienced too much hate from other players towards my choices and there are certain companions that react better to LS choices than others, I think more so in the SW story than the inquisitor's.
