Second only to the command line!
Ive been using Cornerstone for almost a year now, and 2+ years with subversion through the command line. I cant really say that its a true replacement to the CLI, but it definately kept me out of there quiet a few times. Unfortunately, it doesnt have git-svn integration, nor does it have some of those nifty features which can only be achieved over the CLI. If youre picky with how your directory structure is created, with Cornerstone, each folder created is considered a revision, while in the CLI, you can do something like:
svn mkdir --parents --username foobar file:///path/to/repo/myproject/{trunk,tags,branches} -m "Initial directory structure"
and have all those folders created under a single revision. In any case, the UI is user-friendly to the point where non-developers can just go ahead and create a repo on the spot. Developers will really appreciate how much time they can save with common tasks, so that they can focus on their work, rather than typing out long commands.
Great job guys.
