I'm one of the earliest GitHub users, have run FOSS projects, etc. Sapling is absolutely excellent. If anything, the 'sl web' UI alone, which can do rebases/commits, is worth giving it a shot. 'sl web' makes Git rebase look like the dark ages. The UX just has lots and lots of polish in small ways and it has a nice amount of good features. It has fewer verbs than Git, but it's still a bit different from Mercurial. Having a built in 'undo' command that basically always works is nice. I have replaced Git with Sapling (and a similar-but-not-the-same system, Jujutsu) in most of my own personal workflows at this time. If that's a good enough endorsement for you, then I suggest trying it out. You might be surprised.
