Actually, decorators are used when you know, and compile time, what interface the service implements and you want to provide a specific object, implementing that interface, as the interceptor (the wrapper around the core service implementation).
Advice is used when you want to dynamically analyze the service interface, whatever it is, adding ComponentMethodAdvice to individual methods. Making specific changes to a known interface is easier using decoration, such as extending a known existing service to add new features. On the other hand, wide-ranging concerns (such as logging or transaction management or security) can be handled best using advice. Unfortunately, they don't mix, due to the evolution of the underlying APIs (decoration was implemented first, advice came a couple of years later). The end result is that all decoration executes before any advice, with the core service implementation being at the end of the chain.
