I also use % and on long trips the Energy screen, toggling the calculation period. After all, both % and distance are driven by algorithms, but the % algorithms tend to be less prone to error.
Several of my acquaintances prefer distance, simply maintaining remaining trip distance higher than remaning available distance. I understand that preference.
My own preferences are probably conditioned by years flying long distances in airplanes, where energy consumption is largest at the beginning and declines as fuel burns off. Wind and weather are always large factors in planning and flight. When I first began driving Tesla, in 2013, I just transferred my airplane habits, so always considered altitude changes, wind, driving speed, load, precipitation and temperature. Now, in 2020, all that is vast overkill because there are abundant superchargers and other options, so it simply tends to be irrelevant. Old habits die ahrd, so I continue in my traditional ways.
Today it simply doesn't matter much almost anywhere in North America or Europe, and in the most populous parts of everywhere from Japan and China to New Zealand and Australia. When one leaves those area, trip planning becomes a more complex process, so the choice between distance or % still becomes one of personal preference.
