[chef] Formal comparison between chef and other tools

[Daniel Cukier < >]

I'm writing paper about the software I'm developing, which uses chef as its CM tool.

I'm having some difficulties to demonstrate / prove in the paper why did I choose chef and why it is better then other CM tools.

The only paper I found comparing CM tools was this: 

http://www.usenix.org/events/lisa10/tech/full_papers/Delaet.pdf

And if you go through it, you will find that other tools are better evaluated than chef.

I love chef and I wish I could demonstrate that it at least as good as the best tools available. 

Does anybody has any reference that could help me?

Or what are the arguments in the paper above that does not cover the best parts of chef?

Thanks for any help
