Although closed, this SO post can help you understand the differences between Jackson and GSON. Which one is "best" depends on what is important for you.

Btw, although the announced 5 minutes needed to read that document is maybe a bit short, it gives a complete overview of the different ways Jackson can be used. You'll also notice that the examples given do not use annotations.
