Multi-Hit skills don't partially hit in V against one target. So there's no chance Andalucia will miss if it already hit the target.
The main difference between Matador and Artemis is that Matador's passive makes his critical hits instant kill so you build him as mob killing machine while artemis deals more hits but it's pure damage. She also has two more unique skills, a two tier rakunda and a high dizzy phys skill which I think are honestly more valuable than her unique. She also gets a passive where she can't be pierced when guarding but it's pretty situational.
