I think the surpasses the feats granted by the strength of a 100 seal. I don't think those regeneration abilities stack though, or at least not very well. Hashirama's healing was so strong due to massive chakra reserves and strong lifeforce. The Kurama, Ashura and Uzumaki aspects all seem to grant these same effects. These overlaps would help to some degree, but i don't see a massive synergy here.

Anyway, Naruto couldn't regenerate an arm so it seems limbs are outside his capacity. This also means he's not quite up there with a TTJ. We haven't seen him cut in half so we don't quite know if that matches the Strength of a Hundred Seal.
