Yun Jin vs Candace

I pulled mualani last week and im having a lot of fun with her, my team consists of her, xiangling, kachina (with the new natlan support set) and zhongli (mostly for mining tbh, also geo resonance is nice). Recently i discovered Xilonens kit and decided i will pull for her. So, when 5.1 comes, my mualani team will be Mualani/Xiangling/Xilonen and someone else who im still trying to figure it out.

Since most of Mualanis dmg comes from her NA, im between yun jin and candace. yes, i know that kazuha would give her a bigger buff, but i already use kazuha in like 4 different teams. The main reason im excited for Xilonen is because i wont be chained to kazuha so much anymore, i see no reason to use both of them together, nothing in this game is that hard anyways.

I understand that Yun Jins NA buff is bigger than Candaces, but in this team i wont be always protected by a shield, so the geo resonance wont be as usefull, unlike the hydro resonance. Also, with Candace I will be able to use mualanis burst in every rotation i think. So, any thoughts?

PS: my Yun Jin is C6 and my candace is C4
