I don't know if I can offer much in your decision making journey. I have shot the S&W 686 and the Colt Python, both of which I liked, but neither of which I have ever owned.
When I think about a revolver, I think about something truly epic. Like Red Dawn - The entire crew gets bows/arrows, hunting rifles from the gun store and they make a go of it against the invading Russians.
And there is Patrick Swayze with his father's hand me down Colt Single Action Army that is his personal "Justice" piece throughout the movie. .45 Long Colt and ivory handles..... *drools* It was just MANLY, because Patrick made it that way, using it to extract final payment on debts due.
The pistol itself was from the personal collection of the director, which I always thought was really cool.
I think the right revolver just calls to you and you will know it when you come across it. Especially if you don't have one already.
Good luck with the search!
