I have used Black Pixel's Versions app for around a decade. It's probably the best Subversion client I've ever used. Versions made it easy to work with subversion, slice and dice my repos so I could work on projects in my team's idiosyncratic way, and was always rock solid when I needed it.
But as of a few months ago, my last Subversion-using team moved their last Subversion project to git. As much as I love Versions, We've moved on.
But don't expect me to stop using Kaleidoscope any time soon.
