Bullet selection is the key
The .357 has all the power, punch, and penetration you need for everything but the biggest animals, IF you are using the right bullet. And current factory loads are not the key to getting the most out of the cartridge, unless you shop very carefully, and are willing to pay.
Back in the late 1930s, some insanely huge critters, including really large bears were taken by hunters using the .357 Magnum. The guns were N frame S&Ws, with longer barrels (6, & 8 3/8"), and the loads were smokin' hot by todays standards. Advertsied was a 158gr @ 1550fps (from the 8"), and they got it! Shoot those loads out of a K frame (or smaller) and you will likely need a small mallet to get the cases out!
With the advent of the K frame size guns (and smaller), and the popularity of the 125gr JHP for anti personnel use, loads for the .357 have been "reduced" over the years to present levels. Handloading (in suitable guns) can get you back up there, but don't expect to be able to shoot thousands of these loads either. There's no free lunch.
If you might have to shoot through something (like a car door) the .357 will perform better than a .45ACP. The hottest 9mm loads end where the .357 begins, and offer nothing except additional capacity.
I have 44s and 45s, 9mms and .357s. And in direct opposition to some, I see no role for tiny compact .357s. I find the bark, and blast to be bad, and recoil from a pocket 357 is worse (to me) than a .44. I can get back on target faster shooting a big 44 than I can with a J frame size .357. Add to that that much of the .357s power cannot be obtained from a pocket gun, so I see no use to getting just a little more velocity at such a large cost.
Its a very personal decision, and your particular factors are more important than the small difference in performance. My situation is not yours. The one advantage to pocket size .357s is that you don't have to shoot .357s out of them.
