I don't do webdev, but have primarily used Python for 10+ years. I've dabbled in both Rails and Django and agree with the parent's points. I would have stated them myself, but it was probably 5 years ago and it sounds like not much has changed. The arguments might be subjective, but they all ring true to me.

I thought Django Admin was cool when I first set it up, but as soon as I hit a few of the issues the parent mentioned, Admin broke or became irrelevant.
