I'd say Ganyu's C1 is really weak, unless you don't use any res shredding and are undergeared with zero particle team mates.
C2 is the one giving good particles but is kinda a setup for C6 coz you don't need that many with Ganyu's good regen, low cost.

Between the C1s of Ganyu and Kokomi I was actually trying to get Kokomi's coz that's +1 apply, +1 heal/damage and elimination of the need to dash/jump cancel her attacks. Not that rolling helped me, 60 rolls (71 or so into 50% pity) and no Dori or 5*s, so I had to give up for Nilou/Nahida.-
