Best for most newborns: Chicco KeyFit 35. It is the only dedicated infant seat in this group, so it is easier to carry, easier to click in/out of a base, and generally the most convenient choice for the first months.

Choose Graco 4Ever or Britax One4Life only if you specifically want one seat that stays installed in the car and can be used for many stages. Between those two, Britax One4Life is the more comfort-and-installation-focused pick, while Graco 4Ever is the more value-oriented long-term pick.

Bottom line: for a newborn today, pick Chicco KeyFit 35 unless you are intentionally skipping the detachable infant-carrier stage.
