You can say what you like about which is more versatile. I will choose the .44 Magnum over a .357 Magnum every time. And I will tell you why.
One day at a firing range there was an elder gentleman shooting a S&W .44 Magnum. I was shooting my XD9 and was with a friend. He was asking me what that guy down there is shooting, and I said a .44 Magnum it looks like.
I then mentioned how I'd never own one, blah, blah, blah. This was me telling my friend this blasphemy against the .44. I never had any experience with one.
When we were leaving the elder man said to me, "come here son. I want to share something with you." I was shaking in my shoes. My friend was there, I thought I had pissed off the old gent, etc. He just loaded up the cylinder and said, "shoot these, and tell me what you think when you're done." So, I popped off all six. He had loaded it down to a pleasant non-snappy recoil. Way less snappy than my 9mm. It was very accurate, and I instantly fell in love with the cartridge. I ended up with a Ruger SBH and not a S&W double action, but nevertheless I loved the mild to wild factor. Even the mild would do what most people would want to do.
It was nice having that power with little recoil and great accuracy.
To end the story: The old gent just smiled when I handed it back to him, and he said, "Now what was that you were saying about a .44 Magnum?"
