I too have both Handis in .44 and .357. My two .357s are Maxis and the .44 is a supermag. I wouldn't hesitate to take a deer inside 100 yards with either .357 or .44 mag factory loads. Both will kill cleanly. As has been said a million times before....it's shot placement that counts.
I like the Maxis because they shoot the .38s and mags well too. To me, they're more economical than the .44 supermag, even though it will shoot .44 special, .44 Russian, .44 Mag and .44 supermag. Also, just now, brass for the .44 super is about non-existant till Starline makes another run. There's some on Gunbroker right now, but the price is high even for the opening bid.
