actually your post made me reconsider. If samehada can only absorb pure chakra easily then third wins, as his chakra is nature transformed into lightning chakra. And also, bee's V2 lariat blasted through kisame and samehada and 1 finger spear seems more powerful than V2 lariat.no, Samehada could barely take a fireball from itachi. It can absorb pure chakra but not much else.
