From what I've heard you can do more layers on the go than the baby. I'm sure there are limitations on the size just like there would be the go verses the large one. I love my go. I use the raq die the most. I buy lots of flannel when it's on sale; make up a bunch of blocks and then store them in a container and then when at the last minute when I need a quilt/gift I pull out the blocks and design the quilt and it's done in a matter of a couple of hours if that. The time saved not having to snip all of those edges by itself makes it worth it. I would love to have th larger one but no space even when it's on sale. Check their websites to compare
