My favorite ( might just be my most frequently shot handgun of all) is my 2" square butt nickel model 34-1.
I always preferred the look of square butts , they look more classic.
I had been searching for a 2" square but for about 5 years, then stumbled into the one I have. Was really wanting blue, but after not even seeing one for sale ( at a not insane price anyway) for so long I bit on the nickel.
It has possibly the best trigger I have ever felt on a J frame, and no misfire issues. It also doesn't suffer from overly tight chambers and trouble extracting. Surprisingly accurate ( hitting pepper poppers set up at my club at 100 yards is so routine it almost gets boring)
When my schedule permits, I shoot a steel challenge match and often show up with the 2" 34-1 as my gun for the match. I never finish last ( typically middle of the pack for the iron sight pistol class) and rarely need to use the 6th round in the cylinder because I missed.
