Not all of them have had opportunities to act, so its really an unfair question.
Edit: To be fair I will answer to the best of my ability
1.Yoona- Its not a coincidence that she has the most 表演 jobs, now to be honest. I don't like her 表演 too much because it doesn't seem challenging, but people say she has matured as a actor.

link 2.Sooyoung- Again not a 粉丝 of her 表演 but it isn't bad, really its not bad. I think her 表演 could be a good niche for her since she is getting notice for it. I hope she gets a nomination 或者 something.

link 3.Yuri- Despite the obvious cringe worthy 表演 it was better than others. She shows potential and promise.

link 4.Sunny-I don't know if she is counted as an actress because she also had to sing and act but even still her skills got her nominated for a rookie award. Some critics 说 she shows promise in acting.

link everyone is not really seen in a positive light when it comes to 表演 或者 they haven't acted in a while
