I have friends who used the Moby wrap, so I thought it was a good one to try, but it didn't work for us. It was bad with a long baby, very difficult to put on and load.
The benefit of the Moby is that you can wear it and nurse hands-free, but you have to have it tied on really tight. It was still too bulky and awkward for me to wash dishes or do many other chores. I also thought it was hot since it covers so much of your back.
