To start with, I think both of them need another editing pass or two.
The first one has some atmosphere, but feels more like it's introducing a world, not a character. The second one just feels more like vague rambling.
My suggestion, dump both. I also think you should consider whether you really need, or should, start a collection with an introduction to a character that's only in 1/3rd of the stories. If you really think you need to stop and take time to explain more about the character and the world he lives in before people get to the actual stories, you may want to take another look at the stories themselves. Each one needs to stand on its own, and the idea that you need to explain things beforehand makes me think they really won't be able to.
Just my two cents.
