Which Tree of Life is more accurate?

I know of two "Tree of Life" websites. For purposes of comparison,
here is how they both show the relationships among the metazoa:
http://www.tolweb.org/Animals/2374
http://www.ucmp.berkeley.edu/phyla/metazoasy.html
The first one is the one I see cited more often; a lot of Wiki articles
link to it. The second is "chattier", and in the example I gave it shows
more detail than the first: It shows Placozoa, Cnidaria, and Bilateria
forming a clade that excludes Ctenophora. It also shows how Porifera is
paraphyletic (is that the right word?) instead of just stating it.
Thing is, I don't know if they have a solid basis for this extra
information, or if they are relying on some decision process that
will always generate a tree of clades regardless of whether there is
enough evidence to eliminate the alternate hypotheses.
