Out of personal experience?
I've flown from Europe to the US, either the thing is round or planes like to make a huge detour over Greenland, plus jet lag and people back home claiming it's already dark etc.
And I've worked on GPS mapping software for 15 years. It works all over the world, so I guess the round ball model is correct! (We did have a slight issue that south of the equator all distances became negative but that was easily fixed)
Actually I was brainwashed from an early age with this
I should put one of these in my kids room as an experiment, see when they catch on :)
