And don't forget the Ergo if you like the idea of something with buckles. The Ergo Sport is much cooler than the normal one and they are easy to get.

Baby Bjorns are pretty awful on the back, even the back support ones are pretty uncomfortable and have a comparatively low weight limit compared to something like an Ergo. The way they distribute the baby's weight has a lot to do with that, all the weight is distributed on the shoulders, whereas an Ergo (and similar carriers) much of the weight is supported on the hips so is distributed more evenly with the wearer's centre of gravity. I don't know anyone who has successfully breastfed in a Bjorn, the fact that the straps covers the breasts kinda makes it extremely difficult if not impossible so I'd love to see Bjorn back up the claim that you can feed in one with an actual demonstration.

HTH!
