I&#x27;ve been using it for the last two years, since our team switched to Git. I like being able to scroll through the commits list, and the ability to easily add hunks or even individual lines by clicking is a vast improvement over `git add -p`.  Also Sourcetree has a UI for doing interactive rebasing, which is GREAT for the same reason.<p>The biggest downside for me is the inability to easily browse the state of a repo at a given commit, like I could with TortoiseHG. I keep around GitExtensions for some of that history browsing.  Also, the security software installed on my work machine insists on inspecting new processes for validation, which unfortunately doesn&#x27;t play well with ST spawning multiple git.exe process trees. Always  pegs my CPU and slows things down. Performance is reasonable on other machines, though.<p>Overall, I find it a useful and valuable tool. I just wish they&#x27;d make real improvements instead of this &quot;replace  a perfectly acceptable UI with a bunch of unreadable gray lines&quot; nonsense they just pulled. I&#x27;m sticking with 1.6.25.
