Jane and Bing are different. They have similar dispositions, and both of them are kind, caring and trusting of their family and close friends. There's something charming about two similar personalities, but they are not identical. Bing values his friend's opinion over his own feelings. Jane doesn't show her feelings right away, but she trusts them completely. Although status is an important part of the novel, The Lizzie Bennet Diaries makes the issue different. Jane becomes busy to get her mind off off Bing and she doesn't sit around waiting for him to return, she changes. So even though Jane and Bing are both kind and caring, they respond to situations very differently.
That's why my favorite ship is tied. Darcy and Lizzie are a conflicting couple. Jane and Bing are a sweet couple. Both of these relationships reflect the personalities of the characters very nicely, and help them grow and learn.
