Hi J.,
Get the Mutsy if you think you're going to have a average to smaller sized baby. I wanted to get the Mutsy but my baby boy is pretty big, (he weighed 19 pounds at 2 1/2 months). I had a girlfriend warn me that it's not a good design for large babies; her daughter outgrew the carrycot at 5 months and before the baby turned one, she was getting uncomfortable in the pushchair.
To accommodate for a big baby, I went with the Bugaboo Frog, and love it. We had to travel interstate during the first month of his life and needed a system that would be comfortable and versetile enough to double as a bassinet while we were away from home. The Bugaboo held up nicely, is very comfortable, and has great resale value when I'm done.
Good luck to you!
