First daughter - name opinions

Very soon we will be welcoming our first child, a baby girl.

We have a short list of names that we’ve narrowed to our favourite two. Olympia (slightly more the front runner) and Eleanor

Olympia is less common than Eleanor so I’m just a little scared of making a mistake.

Give me your opinions on both Olympia and Eleanor.
Also as a sib-set, as if we end up with 2 girls, they very well could be it.
