Which word is more suitable for describing reality?

There can be different kinds of reality. Reality as experienced by dogs, cats, elephants, lions, pigs, snakes, humans, gods, maras or reality as experienced in hell or reality as experienced in heaven or reality as experienced by water born animals or by birds etc., differ widely in their nature. The word I am comfortable using for reality is dhamma. However, sankhara is another word which might be used as all realities are impermanent therefore they must be a sankhara. My question is : Which word - dhamma or sankhara - should be used to translate the meaning of reality from english to pali?
