Two of the UK's most enduringly popular girls' names, both with a soft, flowing sound and a similar era of peak popularity — the choice usually comes down to origin story and nickname preference.
Both are currently the most-used boys' names in several English-speaking countries. Oliver leans slightly more classic/literary; Noah is shorter and more globally portable.
Both short, currently-fashionable UK names — Freya carries Norse mythological weight, while Isla is a Scottish place name that reads as slightly softer and more understated.
