I prefer the Browning type with the button because I believe it is the most reliable purely mechanical single trigger around, but I say that having never had a problem with any of them. I have no problem with the Winchester 23 either. The actual placement of the selector is practically a moot point with me. If I am flushing birds I leave it on open then tighter, if I am shooting doves I generally have plenty of time if I want to switch. For ducks I usually use two fulls anyway.
I just sold my old double trigger Rossi duck double because I must have changed something and the trigger guard started eating me up with heavy loads. Got a new Stevens with a single trigger and no problem.
