The short answer
The Joolz Aer² is the lighter, more compact package: 14.3 lb with a shoulder strap and a fold of 20.9 × 17.3 × 9.2 in, plus a true full-flat recline and newborn use from day one (baby net included). The Bugaboo Butterfly 2 counters with the better push: bigger urban wheels, full suspension, a roomier ergonomic seat rated to 50 lb, and a one-second fold (17.6 × 9.6 × 21.8 in) — at 16 lb and typically $499 vs the Joolz's $579.

Where the Aer² wins: weight, fold, newborn
At 14.3 lb the Aer² is nearly two pounds lighter than the Butterfly 2, and its flat 20.9 × 17.3 × 9.2-inch fold slides into an overhead bin or a hallway closet with less wrestling. It's also the stronger newborn bet: Joolz rates it from birth, ships a baby net for newborn use, sells a foldable cot, and the seat reclines truly flat — handy if this is your only stroller for the first year. The integrated shoulder strap makes gate changes and stairwell carries genuinely one-handed.
Where the Butterfly 2 wins: the ride
Bugaboo tuned the Butterfly 2 like a small full-size stroller: full suspension, larger urban wheels, and the most generous seat in its class, rated to 50 lb to about age four. Parents who log serious sidewalk miles tend to prefer its push, and the one-second fold is the fastest here even if the folded package is slightly bulkier. It also usually costs $80 less at list ($499 vs $579). What you give up: two pounds of carrying weight and the true lie-flat recline.
Still deciding? Answer three questions.
Our verdict
Buy the Joolz Aer² if it will be your primary stroller from birth, or you're a frequent flyer who lifts it into bins every trip. The lighter chassis, smaller flat fold, and genuine full-flat recline justify the premium over the Butterfly 2 for travel-first families.
Buy the Bugaboo Butterfly 2 if your week is mostly pavement with planes sprinkled in. The suspension, bigger wheels, and roomiest-in-class seat make it the better everyday pusher, the fold is faster, and it typically costs less.
Tie-breaker: child under 6 months now or 25+ flights a year → Aer². Daily sidewalk miles, older toddler, budget-conscious → Butterfly 2.
