I'd be a Jedi Knight. Why? Because you stop being -you- when you turn to the Dark Side, you become a monster wearing an old meatsuit. The Dark Side is corrupting, it drives you mad as a hatter. Make no mistake, Light and Dark are not Passion versus Serenity, it's very much Good and Evil. The Dark Side is Evil with a capital E. Is it fueled with strong emotion - anger, fear, hatred? Yes. But it is not those emotions. The Dark Side will twist you and warp you until you're barely a Human being. The Dark Side consumes.
Now, the Light Side...pretty much requires you to maintain control over your darker emotions. That's about it. It asks very little of you. Sure, the Jedi Order of old tried to maintain that control by suppressing all emotion, but that's not the only or best way to do it.
Also, Gray Jedi are bullshit. You can't be a social darksider, you're either drunk on it or you're not wielding it.
