Mizuki set?

Right now I have her on gilded dreams and in combat I can get like 1500 ish em

I’ve been saving my elixir to craft the new stellar set but it seems like everyone’s changed their minds on it being good? Is it an investment thing where it’s only good at high cons or is it genuinely way worse than gilded or 2 pc em

C3 Mizuki with sig
C6 faru with elegy and vv
Cmc & odette with instructors and the stellar support set
