One major omission from the list of template engines is Jinja2 (http://jinja.pocoo.org/) for Python. It's right up there with Mako in terms of being powerful and fast, and you can do some seriously amazing things with it.

Also, my experience with "low-logic" templates like Mustache is that they actually impede MVC by requiring you to move simple code that is really only used for display back into your models and other application code.
