It's better to have the most sunlight during you waking hours, which tend to be later in the day. People don't wake up at 6am and go to bed at 6pm, more like wake at 7 and go to bed at 11.
Maybe you and your social circle. I get to work at 6:30 AM; despite being fairly far south in the US, I wake up in full night and drive to work in nautical twilight around the winter solstice.
Even in summer, I wake just before the beginning of civil twilight.
