I have two favorites, both equal. One ia a fun, perfect packin' pistol, a stainless Ruger new model Blackhawk 4 5/8 in. bbl .45 LC. The serious hunter is my Freedom Arms model 83.454 Casull 7 1/2 in. bbl, both carried in shoulder holsters. My Blackhawk has only a .002 Cylinder gap (rare for a factory gun), but the cylinder throats were way undersized, so had them reamed to .4525, and had a gunsmith friend take out the trigger take-up and install a wolf spring kit. It is one sweet shooter. Nothing needed for the FA .454, as they are perfect from the factory. Also a very sweet shooter.
Next mod to the blackhawk will be a stainless Bisley grip frame to help tame heavy load recoil, and it will be sweeter yet!
