I have owned both in .41mag. I would take a Redhawk over a Blackhawk any day. If you buy a Blackhawk with a good trigger right out of the box that doesn't need a little help, you are lucky or something.
I worked on my Redhhawk trigger myself. It wasn't too hard because of the design. I'm not suggesting that you do it, but just have it done. Believe me, you will have to do it on the Blackhawk too.
If you are used to shooting heavy loads in the Red, then you most likely won't appreciate the recoil of a standard grip Black. If you go the single action route, get a Bisley. The grip will make the recoil much more managable AND less painful.
I cannot keep the hammer from chewing the web out of my hand with heavy hunting loads. The first Black I ever bought was/is a 4 5/8" barrel. I decided to run some 300gr hot rod loads through it that I had developed for my Red. I came away from it bloody with a little flap of skin hanging from the web of my hand. In the Red, with a Pachmayr grip on it, I thought it was fun. It leaves a pretty good red mark on my hand, but no blood.
I only shoot 215gr loads to a 1000fps or less in the Black. Not a bad deer load if that is what your after.
Another advantage over the Black is the interchangable front sight on the Red.
That is my experience and my opinion. Yours may vary......................
