I have a few slings/carriers.

I found the Close Carrier the best for when Eden was a newborn, absolutely fantastic, and not as fiddly as the HAB.
I have the Ergo as well, but have a problem with it being a bit short in the back for my liking, I feel like my kids are going to fall out - but they are really long kids.
I also have a Hot Sling, which is good for just round the house, but I wouldn't wear it for too long, pulls at my shoulder and neck too much.
I have the Baby Hawk Oh Snap, which is good from 6 months up, however isn't a very good carrier for me because it crosses over the back when in front carry, and it annoys me. Plus its hard for me to adjust so I'm selling that.
I have a Silly Goose Baby Mei Tai - and I like that one, however am selling it, but would be good for newborns, and I still carry DS in it, and he's nearly 3.5 years old. Its good because its got an adjustable bottom on it, so to adjust between a newborn butt size and a toddler butt size.
I have a Kleinsmekker (which is why I'm selling the SGB Mei Tai) and it is by far the most comfortable carrier. Hard to get hold of and VERY expensive (I got mine for $275, the person originally paid $330 for it brand new)

I still want a soft structured carrier though - but since I don't like the BH or Ergo, I'm thinking of getting a Beco Butterfly II. They have a longer back than the Ergo, and they look really easy to adjust. Plus if you have a newborn, they really are supporting the baby in a little pouch type thing, so no worries about bubs falling out.

I think that covers it...
