While i do think she was portrayed as such in naruto, i have never agreed with the notion of people with 0 long range abilities could be considered overall strongest just cause of raw strength, but it is what it is. I don’t think konan could take her tbh simply because of byakugo, Mei and temari are probably the best bets as kurotsuchi hasn’t been confirmed to have jinton and any other kunoichi isn’t really worth mentioning (kushinas been dead, plus other than some inherent op abilities here and there we have no idea how she fought) but Mei can only win in a dumbluck scenario, and I doubt temaris got the reserves to exhaust tsunade, considering what she did to edo 3rd ay tho if she did have some kind of monstrous reserves she’d be a tough fight with all wide spread razor sharp wind jutsus, or at least that’s my long ass .02
