Hard to make a bad choice with the two calibers. I find that the .44 is, for me, a better choice. I have a Colt Anaconda and a S&W 629.These handle my handgun hunting chores quite well. If and when I get back to a .454, my preference is the Freedom Arms.
The various loads for the .44 handle everything I need to do.
The scope, and a rework by Mag-Na-Port (Stalker), have made the Colt my favorite. Wish I could find a second one. I find that a six-inch barrel is aminimum choice, as these calibers are hunting-only for me.
