I think it's a matter of preference and also a matter of practice. I agree that in a hunting situation the hunter shouldn't think about gathering his brass. Admittedly, that's a hard habit to break.

I have only limited experience in wingshooting. My wingshooting opportunities have been limited to doves and ducks. I can confidently say I prefer ejectors with a shotty. For me it speeds up reloading the gun. I don't care about shotshell hulls, so don't pay attention to where they fly behind me. So I prefer ejectors with a shotgun.

My rifle shooting hasn't been as hurried as wingshooting. I have no experience in herds of large animals or in culling hunts. On my deer hunts with DR's I've never even needed the left barrel.

So I think there are advantages either way, but the most important thing is to practice with what you have and know what is in your hand. Operating a firearm becomes somewhat automatic. "Muscle memory" sets in. Just a few weeks ago I was at the range shooting with a friend. I had three DR's, all with Jones levers. Opening a Jones action is just as automatic as opening a toplever action. My friend offered for me to shoot his toplever double. After firing I was amused at myself trying to find the Jones lever under the trigger guard. It reminded me of how automatic these motions become.
