Spittle is the literary one, and it almost always carries a picture with it: spittle is saliva you can see, usually where you would rather not — at the corner of an old man's mouth, flying out when someone shouts in anger, on the chin of a baby or a sick person. Because of that, spittle nearly always sounds unpleasant or pitiful.
