what are your favorite git guis for linux?

I've been using an old as fuck version of git extensions that runs under mono. love the ui/ux and the especially the modularity of it (e.g. i can run a commit dialog/window by itself without needing to open a full-bodied app that presents all kinds of other info and step through to a specific screen).

What's been annoying for me is its lack of stability... seems like it crashes a lot more over stupid shit (like repositioning the cursor or copy/paste in the commit message text box) than it used to. Since this is the only thing I use mono for, I wouldn't mind getting back space from that either.

while i do use cli sometimes, i'm specifically looking for gui recommendations here. FOSS strongly preferred
