Starting to think more about carriers now.

What is your opinion on the Ergo vs the Baby Bjorn. I have heard that there are hip issues with the Bjorn. But I have also heard that when they're older some prefer the Bjorn for convenience sake.

Do you have either? If not, which one and why as oppose to these two?

I'm looking at the Ergo Sport or the Baby Bjorn Synergy.

Thanks!
