Most of the BIG board fabs give comparisons, like you seek, on their sites. For instance: http://www.merix.com/main_res.html

We have no relationship nor receive benefit from the company referenced in the above link.

Finally, consider immersion tin and immersion silver in addition to the finishes you mentioned.
