The reason for permanent daylight savings (versus permanent standard) is to provide for later sunsets in the winter. By clock time, the sun would be rising later (after 8am in many places) but setting later as well giving people some late afternoon or evening sun. Which is better is ultimately subjective, you get short days in the winter regardless when you live far enough north.

The late sunrise can be more dangerous with a lot more people traveling in the dark (especially if there's mixed vehicle, bike, and pedestrian traffic, like around schools). So that's also something to consider, and a drawback to this particular choice.

Most folks subjectively prefer having light after work because that's when it's more fun to do stuff. Unfortunately, the health impacts are (objectively!) worse under permanent daylight saving time.

I do live far enough north, which is probably part of the reason "daylight savings" strikes me as a bit silly: no arrangement of clocks can work around the fact that there's not enough sunlight for all we want to do in a winter day. Both getting up before dawn and leaving work after sunset are undesirable, but during midwinter you can't avoid either one. I figure you might as well just learn to deal with the darkness, and if you can't, move south until you have enough daylight you don't need to "save" it!

Morning commutes are way less worse than afternoon ones so it makes sense to prioritize later daylight.
