+1 for extractors on SxS shotguns and my two SxS double rifles.

As Der Ami said, this is a personal choice and "you pays your money and takes your choice". I have my reasons.

For what it is worth, my two DG lever guns eject empties and reload multiple rounds; with the second shot almost as fast as a double and with many more rounds if needed.
