Heather vs Sadie
Heather and Sadiecompared 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.
Head to head
Ranks are only compared within one published list and one year. Two ranks from different years, from a boys' and a girls' list, or from different registrars are not comparable, so they are not placed side by side.

Heather and Sadie over time
Heather and Sadie appear together in 2 published lists, across 69 years of shared records. Neither was ahead in more lists than 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.
Heather reached its own highest recorded position earlier in 2 of those lists, and Sadie 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.
