Kinda in need of pulling advice for lucilla

so let me tell you about my account i have

hiyuki lynae chisa
carthe ciac aero rover
phrolova cantarella shorekeeper

as my teams i also have hiyuki carte chisa and phrolova sigs and stringmaster for cantarella

i don’t struggle in any form of endgame content but i want to keep investing into my teams so should i get lucilla? seeing her that isn’t much upgrade over lynae made me think twice so i am making this post to help me decide on it thank you!!!
