Have you seen those studies (for example, Atchely & Fitch 1991, Hillis et al, 
1992) where trees generated via cladistics were matched up with known 
phylogenies?

Of the 135,135 possible trees in Hillis et al, all five methods under 
consideration (parsimony, Fitch-Margoliash, Cavalli-Sforza, neighbor-joining, 
unweighted pair-group) predicted the true phylogeny.

Seems pretty darn accurate in those cases, at least!
