Adam vs Isaac
Adam and Isaac compared 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.

Adam and Isaac over time
Adam and Isaac appear together in 6 published lists, across 213 years of shared records. Adam held the stronger position in more years in 4 of them, Isaac in 2.
The order between them changed and held in 3 of those lists — a change in that published list, never a claim that one name displaced the other.
Adam reached its own highest recorded position earlier in 5 of those lists, Isaac in 1. 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.
