GTD best practices | comparing strenghts with other methods/systems

So I just got started with GTD and found it extremely helpful for me.

Now I am wondering whether there is any best practice/ source of information for convincing my team @ work to apply some GTD techniques (at least some), given that they all have their preferred way of organizing their stuff. Obviously, I don´t want to pose things on them. So I would not want to disregard the fact that there are other methods and systems that work OK for them. Anyone any thoughts, comparisons with other methods/systems that would point out respective strenghts of GTD?

Thanks in advance Joe
