I've shot and tuned many revolvers over the years, shooting a 6" Colt Python for years, but find the S&W best for DA shooting and can have the best single-action trigger out there. They do require a bit more TLC than Rugers, but are more "refined" and the choice of many competitors.
Ruger DAs are harder to tune well, but very rugged. A novice would be hard pressed to screw one up.
Ruger SA triggers can be tuned and balanced to provide a light pull with no backlash. I've done many for metallic silhouette competitions, etc. We did find that, using a lot of heavy magnum loads, Blackhawk and Super Blackhawk cylinders would eventually bulge a bit at the chambers (diameter measured with a micrometer), but everything held together.
