My desktop PC stays on through out the day, but I turn it off when I’m sleeping, mostly because it flashes the power button LED in sleep mode, which sometimes prevents me from sleeping. I usually turn of the monitor for the same reason (LED button stays on).
My macbook is set to sleep/lock itself after some period of inactivity, and when I’m done for the day, I usually just close it. The only time I fully turn it off is when I’m traveling and trying to save as much battery as I can.
