If you are going during an off-peak time I think it makes less of a difference. We usually try and go to the am EMH (and don't arrive right at rope drop) and have found the parks to be pretty empty. I think they tend to get more crowded for evening EMH. So what I do is try and go to AM EMH and avoid the park late in the day that has evening EMH. But I don't revolve my planning that much around them. We only go during non-peak times so I am not sure how things play out during busier weeks.
