For enhanced safety, the front and rear seat shoulder belts of the Subaru Legacy have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Honda Accord doesn’t offer pretensioners for its rear seat belts.
The Legacy 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 Accord doesn’t offer a whiplash protection system.
The Legacy has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.
Both the Legacy and the Accord have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors, rear cross-path warning and driver alert monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Subaru Legacy is safer than the Honda Accord:

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 Legacy is safer than the Accord:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Legacy the rating of “Top Safety Pick” for 2023, a rating granted to only 55 vehicles tested by the IIHS. The Accord last would have qualified as a “Top Safety Pick” in 2022.
