I am a S&W K-frame fan, and I am a Taurus fan as well. I generally like Taurus small frame revolvers a lot, maybe more than S&W. However, that said if I'd ever get another .357mag snub it would probably be the M60 (though I might get a Ruger SP101 as well).
I've noticed that S&W J-frames are generally a bit lighter than the Taurus equivelent. The aluminium .38s are 15oz instead of 17, the .38 steel guns are 20oz or something like that instead of 21, and the .357mag steel guns are 22.5oz instead of 24. At 21oz for a .38spl Taurus or 24oz for a .357mag Taurus that I'll almost always shoot .38spl and .38+P out of I'd rather save the 3oz. At 21 oz for the .38 Taurus or 22.5oz for the S&W that is capable of occasional .357mag and that will never wear out with tons of +Ps I'd live with the extra 1.5oz. With the 605 I had I didn't see the point of keeping it around, it was a tad too heavy for the snub's mission. With a M60 I don't think I'd have that problem.
I love my Taurus 85 and I'll certainly be keeping it. Still, I just might like to pick up a S&W 60LS and a 3" M60 if I can find them. I'd still prefer the .38spl only version, but I'd be more than happy with the .357mag versions if that is all I could find.
