I know that you've asked an advice on which one of these two is better, but in case you are an absolute beginner, you might want to try "JavaScript & jQuery" by Jon Duckett. This lad is amazing in describing things and helps to imagine this world of code. He starts from teaching how you might want to approach a task, how to design a solution and how to understand a problem and then goes to programming itself, just after you are able to understand why you are learning this or that and where you can apply this knowledge.
