The benefits depend to a large extent on where in the time zone you are; if you're in the western part of your time zone, you'll already enjoy the longer summer evenings without DST.
Here in Manitoba we're in the eastern part of the Central time zone, and we observe DST. Our latest sunset (around the summer solstice) will be 21:40.
Saskatchewan, our neighbour to the W, is also in the Central time zone, and does not observe DST. Even so, Maple Creek, in western Saskatchewan, has a latest sunset around 21:30. They don't need the extra hour of daylight there.
So, during Standard time, Manitoba and Saskatchewan are in sync, but during DST we're an hour out.
