Welcome to The High Road.
To answer your question we need to ask one.
Best for what purpose?
"Best," depends on what you want to do with it. "Best" for everything means a compromise, so it's unlikely it will be "best" for any one particular purpose. Obviously the "best" pocket revolver wouldn't be an ideal target gun, and I suspect you don't need something for protection against bears.
Also, do you have a price limit, or is cost not a consideration?
So give us more clues concerning your thinking and our collective membership will come up with some answers.
