Verdict / Final Recommendation

If I had to pick one all-rounder among the above, for most families, it would be the Graco Extend2Fit Convertible Car Seat. It offers excellent rear-facing capacity, strong build, many comfortable features, and good overall user feedback.

If rotating seats are a priority and you can spend more, the Evenflo Revolve360 Slim 2-in-1 is a smart pick. But always check your car space, comfort, and how much weight you’re ok handling.

If you’re more budget conscious but still want over $100 and long-term usage, Century Drive On 3-in-1 offers solid value.
