I don't think there's much difference between the two when it comes to overwintering.
Would I be correct in saying that skipping out on a organic based fert for Fall makes more sense in favor of a synthetic product with slow release or even fast release due to added cost of product....? Pound for pound synthetic has more N value for the dollar.
Especially if a client insists on Spring power racking and haul off...?
In repeated tests....my experience has been a low mow in the Spring and even leaving the debris in place promotes a faster green up than the power racking/ dethacth drill.
Many on lawnsite make a chunk of change on this spring service and regardless of facts or what is best for the lawn...will continue to do this service for cash flow.
