I dont have the valco ion but I do have a valco as well (recent upgrade for DS and when bubs arrives)
I love it, they fold really well and steer really well too. We got heaps of extra with ours and we got a toddler seat that can be put on and it reclines too. I like that the hood is extendable to cover both the new baby (when it arrives) and DS when he's in the toddler seat
