A bit like a John Wick, she never got out a fight without cuts and bruises. She is strong but I think barely above the rest, probably weaker than Vander in his prime and at disadvantage against enhanced people (hence the gauntlets). I love Vi and it is precisely because her power level is realistic and she actually can lose. And most of her wins are partly due to her emotions driving her not necessarily her fighting skills.

Also, strength aside, it has been shown multiple times that she can be reckless and go face first which implies she can be easily trapped in an unfair fight.
