I thought that this simple question has been already asked here on Academia, but it seems to that it did not happen (or, I was not able to find it). So, I will ask it.
You have accomplished some good results in your scientific project, and you want to publish a paper about it. How do you decide you would like it to be published into some conference proceedings, or as a journal article, or as a book chapter?
I am considering that all these three options envisage peer review, and are all top-A destination for your paper.
I work on computer science so any particular advice and opinion in this area are strongly appreciated.
