I've yet to run into the S&W revolver shooter that prefered a Ruger DA. I have met many guys that ditched Rugers for S&W's. Just never the other way around.
I've never "ditched" any gun in favor of some other gun. Every gun has good points and bad points. I own plenty of Rugers and S&W's as well. Actually my stainless Security Six I bought new in 1982 has the most _controllable_ DA trigger pull I own. I've won money over the years doing fancy DA shooting with it. I would amaze them right handed and then bet them I could even do it left handed. And I did. Couldn't do it with anything else I own. That trigger justs "talks to you" perfectly. You can pull it 95% of the way and stop, realign, and gently squeeze. No practical difference in accuracy shooting it that way versus SA.
