In their hottest loadings there is basically no difference between the .41 and .44 mags. The .41 shoots just a little flatter but overall there is little to choose between them.
They both beat the .357 but a hot .357 (and most modern .357 loads are not) is more powerful than most people realize.
The old heavy loadings from the early days of the .357 will wake a guy up. I got used to "box store" factory .357 ammunition when used in medium-to-heavy revolvers, but genuinely stout .357 loads launched from - just for example - a 6" GP-100 are not particularly enjoyable for me these days, though I will still politely shoot about any handgun if someone insists that I try their latest cannon (if it is really unpleasant, I just play the old codger card after the first round by handing it back and doing the "aw, shucks... that really kicks" thing).
