The S&W, holds value better, nicer trigger, very reliable.
The Ruger, less money a, built like a tank will shoot almost anything.
The Taurus's, (if you get a good one) are reliable solid pistols, shoot well, will have the lest resale value down the road and taurus has a bad customer service reputation should repair ever be needed. S&W and Ruger have a fair to good service reputation.
I tend to the S&W revolvers because I like their looks, and how they feel in the hand and in 40 years of revolver shooting have only had one problem with a S&W that the factory took care of rapidly.
