These two rarely land on the same shortlist, because their age ranges barely overlap and their ambitions are completely different.
What it really comes down to
Engineering for older kids vs narrative for younger ones
CrunchLabs targets 8-12 with real mechanical builds. Little Passports targets 3-10 with story-led discovery and much simpler activities. If your child sits in the overlap at 8-10, the question is whether they want to build a machine or follow an adventure.

Our verdict
For any child old enough for CrunchLabs, CrunchLabs is the more substantial product. Little Passports is the better fit below that age, but it is not really an engineering subscription.
