Both are booster car seats — here are their published manufacturer specs side by side.
This compares published manufacturer specs — not safety or fit advice. The seat's manual, your vehicle's manual, NHTSA's tools and a certified CPST are the fit-and-safety authority; always check them before installing.

Useful life

Evenflo Big Kid: Belt-positioning booster convertible between high-back and backless mode (identical weight/height/age requirements printed for both — manual: Evenflo Big Kid/Big Kid LX Booster Seat). Not a harnessed seat. Useful life is set by the expiration date on the manufacture label (no printed number of years). Note: manufacturer PDF filename/URL says 'us_amp' but the actual document is the Big Kid/Big Kid LX manual (confirmed by title page) — Evenflo's 'Amp' product is a different manual, hosted at a URL confusingly named 'bigkid-backless-booster-car-seat'.
That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.

Which is right for my car and child, the Evenflo Big Kid or the Britax Highpoint?
