Madara's perfect susanoo is enough evidence that he has monstrous levels of chakra. The fact that he fought against Hashirama for a day is more evidence. It's simply not comparable to Kakashi, we've seen Hashirama spam clones, high-level ninjutsu across massive areas, etc. No way someone like Kakashi can hold that off.
