The template system rocks if you like handcuffs on your templates - and for some projects that may be the case.

Otherwise it's crippled in comparison to Jinja or Mako - with large amounts of un-Pythonic boilerplate if you want to write template tags.

To an extent you can replace it but again you will have trouble with those "reusable" apps.

I think it's better to keep additional logic in your page view functions instead of letting it bloat the template html. Why use a two pass method to parse your custom template logic into python code when you can just write the python code in the view functions?
