Baby Bjorns are actually not very good for baby. If you look at them, the baby kind of hangs from their crotch which is bad for their hips.
The Moby wrap is very nice, but it has a bit of a learning curve to it (it's a long piece of fabric that you wrap around yourself).
I really like a Mai Tai (I have a Babyhawk).
I think my top suggestion though would be an Ergo. When baby is little, you'll need an infant insert. It's expensive but my 30 lb 2 1/2 year old can still use it so you'll get years out of it.
Good luck!
