Need help with team comp Who is better for abyss C6 Beidou or C2 Kujuo Sara?

Currently I am running Keqing Xingqiu/fischl Bennett and Zhongli. I am pulling Kazuha to replace Xingqiu when he reruns. I noticed Zhongli is not really beneficial in abyss and I have C2 Kujuo Sara and C6 Beidou. Whom should I replace him with?
Thanks.
