I like
April, it has a really sharp, neon 1980's vibe to it.
Wren I see as very feminine and soft, but it could work just as well on a boy too, I could see that.
I've never met a real
Wren, but in a comic strip I sometimes read, there are siblings named
Zoe,
Hamish and
Wren. That's a neat set.
I'd use
Wren.
April is a tad bland for me, but if my SO was crazy about it, I could deal.
