Depends on the barrel length and the powder charge/chamber pressure.
45ACP in standard military 230grain hardball is actually pretty darn weak, theoretically as muzzle energy goes.
357 magnum does very VERY poorly in very short barrels. 357 magnum performance is reduced more drastically by shortened barrels than any other round. So much so, that 9mm +P actually outperforms 357mag in very short barrels.
.38 special +P+ does very well...much better than 38, and nearly as well as 45 ACP standard military 230 grain hardball...if you believe in theoretical muzzle energy.
Your list is basically correct, but it gets more complicated than that. You are oversimplifying.
for instance, 9mm+P is basically equal to 40S&W. 38+P is basically equal to 9mm. In very short barrels, the ranking will change somewhat.
You should also add to your list: 38 super, 357 sig, 327 mag, 32 H&R, 45 long colt, and 41 mag.
There are cowboy loads, standard loads, +P loads, and +P+ loads. Some states restrict +P+ loads and higher(+P++, and +P+++) to law enforcement only. But if you handload your own ammo, you can do anything you want. WARNING: not all guns will withstand +P loads or higher. THE GUN COULD EXPLOAD. Check with the manufacturer of the firearm.
I would also reccommend that you investigate 9x23 winchester, and 30 carbine. I personally like these two calibers very much. But they are a bit of a rarity.
