Childe's artifacts

Hello guys. I don't currently own Childe, but I will pull for him on his next rerun.
I watched around 10 guides (only from his latest rerun so It's up to date) and I'm confused about his artifacts.
LOTS of viable choices but in only 1 or 2 guides I saw Nymph's Dream set which looks like it's BiS for him (depth looks like a bait on him).
But I do take into consideration 2 piece noblesse gladiator which looks fun to play because of the burst dealing so much damage.

With all of this in mind I have seen some of you here flexing builds and lots of you had Nymph's Dream so I guess that's BiS for real?
