Which ergobaby carrier is the best all rounder?

[FlyingSoap]

Looking at the ergo baby as seen the best reviews for these, but they’ve loads of different types!

We’d want to use it from newborn to probably 12 months.

Which would be best?

I have only tried my one! But it's the omni 360, works perfectly without an insert for newborns (I think there is a min weight maybe 7lb). We used it to over 2 years old.
Do you have a sling library near you?
