I started using Mercurial and chose MacHg as my GUI of choice, simply because it was the first thing I found when I googled Mercurial Mac GUI. However, I just recently discovered Murky, and TortoiseHg was recently updated for the Mac. Are there any significant reasons I should choose one over the other, or is the decision simply which application's interface I like the best?
This question is sort of subjective, but I've found SourceTree to be a good solution for visualizing your working copy. However, for the most part, I just use the terminal to commit/push/pull/update.
