She couldn't heal Neji or Shikamaru.
She also couldn't protect Konoha with Katsuya and heal them the way Tsunade did.
I would say she's only maybe 50% at Tsunade's level.
Neji was already on death's door and she stabilized Shikamaru, while Tsunade gave him a chakra boost and Naruto motivated him via flashbacks.
@bold- Well, yeah. Tsunade was busy doing that. Two people aren't needed in that circumstance and what Tsunade did was pointless given that Nagato just revived everyone.
Nah, she surpassed Tsunade given that the character descriptions for The Last say that she's the top medical nin in Konoha at age 19.
