From my experience, the Close Parent carrier is brilliant - its easy to put on and take off on your own, easy to put baby in etc and my son loves it. It normally sends him to sleep! Its very comfy for me to wear, and its not too bulky if you take baby out when you are on the plane. I just love mine, 100% recommended!
We also bought the Morph carrier from Mamas and Papas, for my husband to use as he thought the Close was a bit girlie! We have had nothing but trouble with the Morph - including one of the clips which fasten the baby pod to the harness actually came off when my son was in the carrier!! He only weighed 10lb at the time. We took it back to the M&P store where we bought it and they couldn't have been less helpful. I'm going to write the full review soon to warn other people - so for me I would never put my baby in a M&P's carrier again.
I hope that helps!
