You don't compare calibers. You compare bullet weight, design, velocity, and terminal effect, and see if somewhere in the caliber a combination exists that makes you warm and fuzzy.
I forgot to mention you have to factor in the gun, barrel length, and intended use.
What you can compare caliber wise is the variety of the above available, and, if it will do what you want.
If you like light bullets, .357.
If you like heavy bullets over 180 grains, the .357 isn't real good.
If you think the old Colt Standard, 260 grains at 950 fps is the Holy Grail,
then you want a .45 ACP.
If you like penetration, you need to tailor bullet design, weight and powder charge to create optimal wound channel with expansion, and penetration.
If you like high velocity light, both will do it, but easier with the 357.
