The Sith are even more flawed than the Jedi for anyone above the age of 15, or who aren't fedorafags. One of the great things about the Galactic Empire is it's atheistic, so I don't have to shit on it for its materialistic spiritual philosophy.
The only downside to the Jedi is they're liberal ideologues*, although it's treated as more "knights if feudalism meant a form of democracy", that is, they're not really ideologues outside of what they profess to believe, often being critical of the system, much like how a knight may hold his liege lord in contempt but continue to fight for him as per the knightly way. Jedi protecting an empire would be a dream come true.
*Where exactly is it stated that the Jedi are pacifists? Although they obviously prefer fighting only when absolutely necessary, I don't think they've ever been described as pacifists in the films. If they are, then that's another issue with them, but Sith ideology is so fundamentally broken (besides that the Force sees them as an unnatural element that disrupts the balance of the Force and therefore evil) that the Jedi will always be preferable.
