Anyone who is less excited about the safe arrival of a baby because they knew beforehand that it was a boy or girl than if they didn't really had their priorities wrong. I can't believe anyone thinks the arrival of a baby is better news when you didn't know before . If the baby has arrived safely then how can anything else top that?
It is a surprise whenever you find out, it's just that some people (like me) choose to find out during pregnancy when things are a bit dull and it feels like a long slog to the arrival of the baby. It was still a surprise to be told that DC1 was a boy and DC2 is likely to be a girl.
And I didn't do it for gender stereotyping the bedroom. DS wears pink, amongst many other colours, if he wants, and has a brightly coloured but completely gender-neutral bedroom. DD's bedroom decor was all picked out before we knew that she is likely to be a DD.
We just wanted to know something about our babies halfway through pregnancy. That is no better or worse than finding out at the birth, but lots of people who wait have told me how I've ruined it for myself... So bloody judgmental!
Plus personally one reason to find out was I hate using or hearing the word "it" or something twee like button/bump/poppet/tigger to refer to a baby in utero. So I wanted to know whether to refer to him or her for my own DCs. It also helped in labour saying to myself "come on meg, you're going to see him soon" - felt so much more personal, and human, than "you're going to see it soon"
So no, I haven't regretted it and neither has DH.
