The system that grows from newborn bassinet to two or even three kids. Expensive, heavy, and the one people keep across multiple babies.
The Vista is the splurge that can actually pay off, because it's less a stroller than a platform: it comes with a bassinet (a safe flat surface for newborn naps and overnight use), accepts a RumbleSeat and PiggyBack board for a second and third rider, and clicks the Mesa Max infant seat on top. If you're planning more than one kid close together, the cost-per-year math gets reasonable. Trade-offs: it's heavy, the folded footprint is large, and single-kid families are paying for expandability they may never use. Skip it if you're one-and-done or space-constrained.
