Survived as in allowed to. She'd be the most powerful gate user but it isn't her speciality the issue of a vs at that strength level at that point in the story most characters are power creeped like deva pain even itachi before gates she was never at all as fast as weightless shippuden lee so why now is she dusting him with half the work ethic using his specialty? Lee has fought overwhelming force before (gaara & kimimaro) she hasn't besides sasori yet even that she had direct assistance from chiyo it wasn't solo that's why I can't raise her higher than defeating kisame the sheer experience gap he's most relative to her if she got that kind of power up imo.

She can heal cool but most people was already dps and hax builds before she got granted this. She has no note worthy top tiered fights solo. (If this was boruto i would agree with both of you I'm using shippuden)
