Based on reviews posted on popular review sites as well as from Nest Protect's website, Nest Protect performs very well in terms of long lifespan relative to other smart smoke detector brands.
The review site toptenreviews.com gives Nest Protect excellent ratings for long lifespan in a review posted on its website. From this review:
As required by law, the sensors in the Nest Protect smoke alarm have a life expectancy of 10 years, so you won’t have to worry about replacing it for a decade. Unfortunately, the device warranty is only two years, unlike the 10-year warranties of the First Alert Onelink and Kidde KN-COSM-B-RF.
The review site trustedreviews.com gives Nest Protect excellent ratings for long lifespan in a review posted on its website. Here's a brief quote from this review:
Battery life on the AA-powered model depends on usage, but it should easily see you through five years. When batteries are low, you’ll receive a notification – you won’t have to hunt around your home looking for that beeping model. Nest Protect is designed to last 10 years, after which it should be replaced; the same is true of all smoke detectors.

This smoke alarm has a device lifetime of 10 years, matched by a warranty of the same length. This is quite impressive, considering more expensive smart smoke detectors such as the Nest Protect and Halo+ have much more limited warranty coverage.

Based on reviews posted on popular review sites as well as from First Alert Onlink Safe and Sound's website, First Alert Onlink Safe and Sound performs very well in terms of long lifespan relative to other smart smoke detector brands.
The review site pcmag.com gives First Alert Onlink Safe and Sound excellent ratings for long lifespan in a review posted on its website. Specifically, this reviewer pointed out the following:
This is used when the alarm reaches its end of life after 10 years of use. The power jack is compatible with other First Alert alarms, but the Safe & Sound comes with two additional adapters that will fit most popular third-party power connectors. It also comes with a mounting plate and screws, an Alexa quick start guide, and a user manual.
