Billy and Cianancompared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.

The order between them changed and held in 2 of those lists — a change in that published list, never a claim that one name displaced the other.
Cianan reached its own highest recorded position earlier in 3 of those lists, and Billy in none. Each position is a place inside its own list, so this compares when they peaked and never how high.
Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.
