I witched to Mercurial about a year ago. Before that, I used Subversion, and I used it only through the gui tools.
But when switching to Mercurial, the gui tools weren't as good, so I learned how to use it via the command line. And, to my surprise, I found that it's much easier to use the command-line rather than the gui tools. Everything goes much faster.
So if you're a Windows dev, like me, and have never tried solely using the command-line tools before, I suggest you give it a shot. You may be surprised like I was.
