It's entirely the same from what I can tell in terms of the exp usage. You either grind a sword to lvl99 and after Kiwame it ends up being lvl39 (?) sword, or you grind it till lvl60 and after Kiwame it's lvl1. I don't know how high post Kiwame stats are, or how well the swords perform at lower levels, so in case they aren't significantly higher it might be better to grind the swords to lvl99 first so you'll have a functional Tantou post Kiwame, and not a potentially weak baby that has to drag itself getting 100 exp on early maps with now ridiculously huge exp gap needed for leveling up. On the other hand, some screenshots of post Kiwame Tantou stats were posted earlier and, if they are real, the Tantou may be ridiculously strong, so in the end they may perform perfectly well even at lvl1.

tl;dr ¯\_(ツ)_/¯
