Car seat/stroller

Picked out the car seat as Nuna Pipa and now debating between these strollers:

Uppababy Vista

Agio z4 peg Perego

Nuna mixx

Both the uppababy vista and agio z4 can be used with Nuna Pipa with adapters. And both can accommodate a growing family in case we do have more than 1 (currently pregnant with #1)

Not sure if we will or not, but would probably be good to have that option

Otherwise the nuna mixx looks like a great option and since the Pipa is same brand, it would be easy to get this as a travel system for lower cost.

But then if a #2 comes along, we would have to get a whole new system.

Agio z4 looks like a fantastic stroller, made in Italy, yet I don’t know anyone who has had this nor is it listed on popular pregnancy sites.

Uppababy is everywhere - but is it that good?

Does anyone have experience with these 3 brands?

Thank you!
