I love .44 mag. Get a regular redhawk vs a SRH if going .44 though, better balance and looks. I have a SRH that I had snubbed that is pretty fun. Either will serve you well, but the Redhawk is a little less extreme looking and would be easier to pack around. The SRH was meant as a replacement for the RH initially because of barrel separation problems, but the problem was solved and people liked both so Ruger still makes both, though the cylinders are identical. Super heavy loads can be used in either.
My main bitch with Ruger is the triggers in them suck. They take alot of work to get them right, and changing one thing means having to grind/polish elsewhere. Some folks can do it, but for most it is best left up to a smith to get it right. I have spent a week of afternoons polishing and trimming springs, and ordering parts to get it right.
.44 mag is the biggest bang for the buck in HG cartridges. Yea, there are bigger and more powerful rounds out there, but .44 mag is so common that you can get the specialty heavy loads for what factory loadings of .454 or .500 go for.
In reality .44 is cheap enough to plink with, with cheap loads going to $15 for 50 rounds, the 320 gr hardcast bear loads are impressive to shoot, and handloading for it is fun. It could also perform double duty as a HD gun and as a hunting/bear defense gun depending on loads for those who are not inclined to buy a gun for every niche.
