I would say that Kyle consistantly maintains a sense of right and wrong as well as honor that sets him apart from Stan in most episodes. Although you're right, they can be pretty damn similar.
Amazingly, South Park hasn't lost it yet (episodes such as Broadway Bro Down are proof of that), but it IS showing its age. They should really stop soon, or I'm afraid it'll be a repeat of the Simpsons.
