Question Ranking
Pros
Pro For micro templating
Due to Underscore's optimized performance and ease-of-use it can be deemed as most fit for use in small sections of your code, where you just want a quick and simple template to render your content.
Pro Pre-compilation
Underscore allows you to compile your template once before data is inserted to it.
Pro Language independent
The same template written in Closure would work both on Java as well as javascript.
Pro Well Tested and used by Gmail and Google Docs
Closure Templates being a project created by Google, is extensively used in some of the world's most famous and largest web apps which include Gmail and Google Docs. What this means for you is that you'll be using a Template engine that has not only been intensively tested but also that you'll be in good company, with lots of technical support.
Pro Secure
Closure has been designed keeping most security risks in mind. Templates created using Closure are auto-escaped automatically. Hence you won't have to worry about any XSS attacks.
Pro High Performance
Closure templates do not tend to slow down your site's performance or increase your page load time. They're compiled to extremely efficient JS code so that your page renders extremely fast, whether the templating is done on the client end or the server end.
Cons
Con Not a true templating engine
template in underscore is simply a function which compiles a piece of template into HTML. It's useful for rendering HTML from JSON and it's not very useful when building complex frontend templates.
Con Hard to find what you need in documentation
Docs are pretty, but hard to find exactly what you need. Although language has nice macros, you're going to hate them when they fail and you search for info for half an hour.
Con Strange errors from compiler
You won't get used to them even after a while.
Con Not widely used outside of Google
Closure Templates are mostly used in projects developed by Google and not in projects by third-parties. As such, it's unlikely for further versions to be released or for changes to be merged.
