Hiya, would love to hear others' opinions on these three travel systems. We tried the Flex and Nuna Swiv out in Mama's and Papa's last night and liked both but the Swiv's lightness and 360 wheels slightly won out even though I did prefer the aesthetic of the Flex.
My BIL added the Oyster 3 to the mix as this is what they've been using and he highly recommended it. It is also considerably cheaper than the previous two systems but we've yet to try it out in store.
This is our first baby and the travel system has been the most overwhelming purchase so far!
