Cape Hallet south must certainly be the most spectacular of those three routes.
I've had a burly bearded American (a tradie of some sort) from Antarctica northbound on board after finishing his tenth summer on the ice. Every other flight he'd been in a usap flight (c17 or C130 ) with no windows. He was openly crying with the beauty of the scenery around Mt Melbourne, and that was at 37,000 feet.
But the scenery is even better at 500 feet.
