Do we count jams in the pump and autoloader times?
A couple of days I had a really good spot in an Argentinian dove shoot. Shoot, open the ejecting breechloader, drop in two shells, close, look up and there will be birds there to shoot at. Over and over and over. I think that in that situation the breechloading ejector would at least keep up with the pump. If the pump jams only once then the breechloader would be faster, in my estimation.
When I compete in NSTRA field trials I carry a beat up, pinned wrist, bulged barrel eight pound Parker VH 12ga (non-ejector) choked cylinder and 20 thou. A couple of times a pen raised bob has managed to twice fly through holes in my pattern, then turn and fly back by me. I could not get off a third shot as I was fumbling getting the spent cartridge out of the chamber. Ejectors would have been nice in those two instances. Other than that I have not regretted the lack of ejectors in any of my extractor guns.
