I really don't feel like there is a huge difference between the two size wise.
Ok here is is folded. I couldn't figure out how to lock it when folded. There was nothing in the manual. It's also very large folded. I have a van so that's nbd to me, but I feel like for people that have a smaller car it could take up the whole trunk.
Overall I love it. I think that it will give my daughter the freedom that she wants, but the option to hop on (and be buckled if need be) without being this humongous stroller that gets in the way.
I hope this is helpful!
