If all engines fail, Id be really hesitant to trade altitude for a windmill relight. If they both failed, Id think there could be a high probability of being unable to restart them (fuel starvation/contamination, damage due to ice/birds/whatever). You can always try to restart them when youre below the appropriate ceiling but the altitude (air time) you just traded off its not coming back. Starting the APU is an immediate action. Ask Sully.

And people say no need to practice dead stick landings in the simulator because it will never happen..

Cactus 1539 was 10 years ago today - Had Capt Sully not immediately switched on the APU as both his engines rolled back (this was not a SOP) then he would not have been so successful in landing the aircraft as he did.

The QRH showed reference to close the ditching valve (which was not accomplished) but he and his FO only had about 200 seconds to deal with the whole scenario.

The A310 was not a ferry flight but was a package holiday pax flight from Crete

Took off from Chania for Hannover and a malfunction prevented its gear retraction after take-off.
FD crew elected to go gear down all the way home but the plane eventually ran out of fuel while attempting a diversion to Vienna, crash-landing just short of the runway. No fatalities resulted, although the aircraft was WO

Their FMS showed the expected standard range with gear up without considering the actual gear down drag. They trusted that prognosis and crossed the Alps until they had some glider. Still managed some okay landing.

Incident: ANA B788 at Osaka on Jan 17th 2019, both engines rolled back after landing
Now that's a sight you don't see very often..Think of the ramifications if it happened while airborne.

Think of the safeguards

Depending on the altitude... BA38 in the best of cases
