I prefer morning, but sometimes the weather becomes a factor. Two of my biggest bucks, were shot just past noon. I think, some hunters are tired by noon and quit or move to a new location. The bucks move too, and on more than one occasion, they came my way. During the rut, they move all day and night. The only reason, I hate to hunt in the late evening, I don't like looking for a deer after dark, and having to take care of it. I've had nights, that I didn't get home till midnight. One night a friend and I had to pull a buck across a river, in the dark. It was a shallow mill race, but temps. were mid 20'S. In those days, we hunted from daylight til dark.
Now, at 63 years old, I prefer morning.
