Get lauma or stick to c2 nahida?

Don’t know but someone might ask this already so I’ll leave my question here anyway. I have c2 nahida and I like lauma and kinda want her. However I don’t know if she’s worth getting or not cuz idk if she is worth replacing c2 nahida. Definitely can’t use 3 dendro for this team. So does anyone know any calcs? Would love to replace nahida with lauma but if she is not his bid then I guess I’ll skip her and get flins cons instead. If anyone knows please help me out, thanks!
