I think I read somewhere to change the oil while it's hot so you have a high enough drain velocity to keep solids in suspension.

With that in mind, I choose to change my car's oil using the drain plug. When I change the oil in my boat I have no choice but to use a top-side changer. I try to stroke the pump as quickly as possible to avoid dipping below the "settling velocity".
