I think the RH's have excellent triggers, my 4" also has a smooth, even DA pull and a decent SA break. I don't have a lot of experience with Redhawks, and I was pleasantly surprised at how even the DA pull was when I got my 4" .44. It seems like Bill Ruger hit on a good idea with the single mainspring-rebound spring idea.
A lot of the S&W "die hards" slam the Rugers for "crappy triggers" but I have many Rugers with DA and SA that rival any S&W,and many that will outshoot any of my several S&W's. Believe me, I have my share of Smiths with garbage stagy uneven DA pulls and creepy SA breaks, too.
I don't even really look at S&W's in any caliber above .38 Special........for the big bores and magnums I only go with Rugers.
Heck, I'm at the point now where I hardly even look at S&W's anymore, the last few gun shows I went to I had Ruger wheelgun "tunnel vision" 8)
