Kindle Unpack is just an unpack. The 'epub' it produces from .azw3 files is probably not fully compliant with ePub standards, although with a really good source book it's not very far off.
But it's easy to buy on Amazon and read on nook - just let calibre do the conversion from azw3 to ePub. It's what I do. Only if that produces poor formatting will I bother trying to tweak things, and then it's probably calibre's conversion options that can be the most use.
