Not promoting one tool over another but CA has done quite a bit for Erwin.  They even had a big focus on bug improvments to the point of holding off any improvements... I believe it was around release 4.14.  This made a big difference on bugs with RE and complete compares.  I'm not on the current release so I cannot make comments on it now.

As for the article, good article for a starting point on sizing issues with a database... as the title indicates.  I think the tools mentioned give some basic direction on where to go for further 3rd party help.  Listing out additional resources would have helped keep it from sounding a bit like an advertisement but it makes sense that you would focus on the ones you are familiar with.

Any plans for more indepth articles on the subject?
