Did all that 40 years ago, I wouldn't be interested in a 25acp if they were giving them away. I'd rather have a rock on a string.
Go with the 22LR. The other two are not discernably better in a little short barrel and cost is ridiculous. The 22LR at least you'll shoot it enough to learn all it's low points and pushing it against a person's neck and pulling the trigger it will be just as good or better than the other two.
