I reckon the Miles looks really solid
I’ve travelled overseas with my baby twice with the Joolz Aer, it folds and unfolds one-handedly, is one of the lightest travel prams on the market (just under 7 kgs), fits folded into overhead storage (on international flights haven’t tried on domestic which are smaller planes), is super sturdy and high quality. It still looks like new and we bashed it around on over 7-10 flights and I use it now as my daily errands pram. Can’t recommend enough!
Just bought a babybee mio. Honestly it’s set up in my living room and feels just as good as any other top notch pram I tried out at the stores (nuna, uppababy or bugaboo all comparable in terms of quality). I’m excited to use it. It’s a bit smaller than the Cruz but almost the same
I don’t have either but my best advice would be to compare them all, pros and cons etc.. then decide from there.. good luck :)
