What's your favorite web view for Subversion (SVN) repositories?

Some options:

• Trac It's free/open-source, and widely used. The SVN-browsing part of Trac is here
• bsSvnBrowser - an AJAX'y subversion browser (demo)
• WebSVN - Written in PHP, looks nice (demo)

We use ViewVC internally which works great for our needs.

Much more than just a web interface to svn: Trac -- open source and includes issue tracking and a wiki. Not the easiest thing to set up though.
