Cian and Leroy appear together in 2 published lists, across 48 years of shared records. Cian held the stronger position in more years in 2 of them, Leroy in 0.

In none of those lists did their order change and stay changed.

Leroy reached its own highest recorded position earlier in 2 of those lists, and Cian 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.
