As mentioned above, they are both quality child seats. I have used both in our shop and had no complaints with either one. Another one to consider is the Giant Progeny http://www.giant-bicycles.com/en-US/...ing/211/26908/ It is one of the easiest seats to take on & off and comes with 2 seat liners (boy & girl). The drawback is that it's a little heavier than the others.

Best of luck!
