Santo Fortunato (http://sites.google.com/site/santofortunato/publications2) wrote several interesting articles on the objective evaluation of spectral centrality measures and community detection methods. Particularly, the authors conclude that infomap is the most accurate community detection method for any kind of network presented.

Spectral centrality measures in complex networks:
Community detection algorithms: A comparative analysis:
compares several popular community detection algorithms by testing them on weighted or directed benchmark networks with heterogeneous distribution of degree and community size, and overlapping community structure.
