You are right when you say that I don't know the bcachefs internal, however it still not correct to compare the speed of filesystems when the features aren't comparable.

Anyway I am curious how the snapshot are implemented in bcachefs. Could you share with us more details ? How is scalable the bcachefs solution (btrfs behave well with ~100 snapshots, and with some limits is tolerant with 1000 snapshots)

I can't comment about prediction. I hope that bcachefs will be a good filesystem.
Anyway on of the biggest problem in BTRFS is the huge number of features and their combinations. The most difficult thing is verify that BTRFS behave "not so bad" in every combination.
