Blackwater, & Thumbcocker both have made a lot of excellent points.
I currently own some Super Blackhawks in 44 mag, and one in 480. I also own a few Redhawks, in 44 mag as well as a Super Redhawk in 480. So, I have a fair experience with them.
Strength? All are excellent & will withstand years of use,,, as long as you do not overload them & expect them to do more than designed for. Staying within SAAMI specs,,, you will find they will all be plenty strong.
Find what's the most comfortable to you & go that way.
If you are anywhere near WNC,, you could sample all of mine to see.
