Yes, I should be a better woman. This translation is the most appropriate and accurate statement in spoken English. Other statements will be far-fetched Although you say that you are an excellent woman and others can understand you, it will sound good!

There is a song in English, "Better Man" by Robbie Willand, which contains a lyric that many people are familiar with: You are a better person.
