The Subaru Ascent has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Traverse doesn’t offer knee airbags.
The Ascent 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 Traverse doesn’t offer a whiplash protection system.
With its standard EyeSight, the Subaru Ascent is better at preventing collisions with pedestrians than the Chevrolet Traverse, according to the Insurance Institute for Highway Safety:

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Ascent. But it costs extra on the Traverse.
Both the Ascent and the Traverse have standard driver and passenger frontal airbags, front side-impact 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available around view monitors and driver alert monitors.
