Load Testing and Benchmarking With siege vs wrk

Question

I have been looking around for tools that can help me to do load testing and benchmarking. I found a couple like:

• https://github.com/wg/wrk
• http://www.joedog.org/siege-home/
• https://github.com/rakyll/boom

I'm wondering if anyone has any experience with these tools and have any feedback pros vs cons of these tools. My load stress will include different test cases using DELETE, PUT, GET, POST, etc. headers.
