To some, them's fightin words. Now, I'm not one to get that stirred up, instead I'll just point out that the 357 Magnum is one of the most versatile calibers in existance. I don't think you'll ever see the 327 used for hunting game such as Deer, out of a 20 inch barrel the 357 will knock them down quickly. In addition it's Defense capabilities are not only well established, they are also well recognized. Finally, a 357 Magnum revolver offers the opportunity to shoot what continues to be the most widely used caliber in the world, the 38 spl..
IMO the only weakness of the 357 Magnum is that it's a handful in term of recoil, flash, and blast, in a light weight firearm. The new 327 Magnum is an attempt to exploit this weakness. However, there is one little issue with the 327, that is the little light bullets. Quite simply, if you find the 357 Magnum a bit too much in your featherweight, use some 38 spl. You'll not only reduce the recoil, you'll also have the option of using a heavier bullet.
