I have a Snoozer & a Pet Gear for ZoE. ZoE prefers the Pet Gear. The sides are harder, so she can stand on them and look out better. Also, ZoE tends to turn around alot in her seat at times, and her hair gets horribly tangled on the swivel part of the snoozer strap....have often wondered if anyone else has this problem, given how many people rave about them.
Here's a thread comparing all three.
