If the Sith were consistent and coherent in their philosophy they would be encouraging strength in others, encouraging spirited but fair competition in every aspect of life and acknowledging the right of others to claim freedoms. If you judge the factions solely by their codes, the Jedi come off as foolishly naive to the point of denying reality while the Sith wind up looking like pragmatic realists. A sort of anarcho-capitalist dreamworld would fit perfectly with the Sith creed and the teachings they feed to their new recruits.
The problem is that they don't actually do this. In The Old Republic it's actually possible to play a Sith this way (Light Side Sith Warrior is a very interesting experience, full of very confused enemies wondering why they're still alive after you leave the room), and a couple of the Sith characters do kind of espouse this philosophy, but by and large the Sith are all somewhere between ruthless self-interested sociopaths and tyrannical fascists (or both), using the Sith Code as a justification for being horrible people. I actually agree that you could play a very fun Sith in an RPG, but in general they certainly aren't great neighbors or the kind of people I'd want running an institution I belong to.
Of course, there's certainly something to be said that a non-corrupt Sith society might have some virtues. That just doesn't seem to actually happen in the canon.
