I'll give the standard answer to this very common question.
They're all "good" guns. So you need to try before you buy if at all possible. Check to see if there is a range you can go to that rents guns. These are all pretty common, and they likely have several of them to try.
Now, for a more detailed response, we need a little more information.
What is your experience with guns, and handguns in particular?
Do you have other guns that you would use for "target" practice? A very important part of owning a gun that it appears you want for self defense.
Do you have a way to securely store the weapon?
