The Impreza has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Sentra doesn’t offer a whiplash protection system.
With its standard EyeSight, the Subaru Impreza is better at preventing collisions with pedestrians than the Nissan Sentra, according to the Insurance Institute for Highway Safety:

The Impreza has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Sentra doesn’t offer all-wheel drive.
Both the Impreza and the Sentra have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Subaru Impreza is safer than the Nissan Sentra:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Subaru Impreza is safer than the Sentra:
