At a technical/chemical level, yes. For the rest of us, no, not much. Ceramique is supposed to be non-conducting, while Silver can conduct electricity. AS5 is supposed to be slightly better at transferring heat, but the difference is minimal to nonexistant except at the extreem. (and that's debatable - I've seen people report either one being better than the other)
