50/50
My success rate is 50/50 as well. I perfer mornings because it is easier to deal with getting your deer out after shooting it. However......
The bottom line is you have to be there when the deer are. This is dependant on the time of season. Early in the season the evenings seem best. During the rut, both are good. Late season it switches back to evenings. On average I suspect that evenings win over mornings, but when it comes to november, I believe it to be closer to 50/50.
