Personally I don't think it makes a difference as long as your keyword is in there. I have used both the first and second option and still gotten the pages ranking.
Generally for my own sites, for posts I have the permalink set up to put the post title in the permalink so it ends up looking like the first option. For pages usually I would use the second option. But like I mentioned it doesn't seem to make a difference so this is just my personal preference.
Hope that helps,
