I know there's no canonical evidence and details of Asura's and Indra's powers, but the filler is best we've got, so we use that. In that case, Asura has half of Hagoromo's chakra by birth plus Six Paths Senjutsu gifted to him plus Wood Release and maybe perhaps had Tailed Beast chakra as well, which makes Asura a merger of both of Hashirama's and Naruto's powers, in theory.
