The best method I know for comparing phylogenetic trees
is Joseph Felsenstein's Maximum Likelihood method.
It has excellent statistical credentials.
It may not be practical if the data set is very large.
You also have to give it the n-way alignment as input.
J.F. distributes a package with several different tree methods on,
including max parsimony and max likelihood for DNA and protein:
