Previous longtime sourcetree user. Fork fells way more responsive, has better UX and the same if not more functionality compared to sourcetree. This is super astonishing taken that only two people develop this lovely software. My Highlights:
What sourcetree does better
I switched from Mercurial to Git and was searching for a replacement for TortoiseHg. This was simply the best free Git client I found. The user interface is slick, it's simple and straight forward to use. There is a feedback button in the app, and using it made the developers reply within 2 hours or so - amazing.
It's truly the best Git GUI for Windows / Mac. Easy to use, very powerful and with the great UI
Still great, but not free anymore. Not too pricey at $49 though.
I have been following this Git GUI for a few years, and have tried it a little bit. Program advertises itself as "free", but now latest version has a popup screen "please purchase fork git" where it says you can buy it for 49.99 USD for "Personal and commercial use".

Still early days, but my initial impressions:
Thus far the only git client I've actually enjoyed using.
