Question 2: Which one can be most customized: rubber grips, scopes, breaks, slings....?
The grip stud of the SRH allows for many different grip styles. The factory scope slots are great, and you can remove and reattach the scope without losing zero. You won't need a brake on a 44, and none of them are ready made for one. Get a good holster, slings just get in the way on a revolver.
All that said, I'd also opt for the SBH as I like SA's for hunting. Better trigger and you can still scope it with aftermarket bases.
